| [01:37:38] | ubuntuaddicted: | wagnerrp, mythpreviewgen is not part of mythtv? |
| [01:37:56] | ubuntuaddicted: | or mythdbcon.cpp ? |
| [01:38:06] | wagnerrp: | it is, but that error sounds like some issue with your database server, not mythtv |
| [01:38:48] | ubuntuaddicted: | wagnerrp, it started occurring after I did a dist-upgrade to mythtv 0.26+fixes |
| [01:39:04] | wagnerrp: | did you upgrade mysql libraries at the same time? |
| [01:39:24] | ubuntuaddicted: | wagnerrp, i would think apt-get would do all that for me? |
| [01:44:08] | ubuntuaddicted: | wagnerrp, what are the mysql libraries I should look for? |
| [01:44:23] | wagnerrp: | the ones mythtv hooks into to connect to your mysql server |
| [01:44:24] | ubuntuaddicted: | i just restarted my server as well, just so everything is fresh |
| [01:44:41] | ubuntuaddicted: | wagnerrp, lol, sorry but I have no idea what those would be |

| [15:05:09] | ubuntuaddicted: | man, i wish I could get some help |
| [15:09:16] | sphery: | ubuntuaddicted: notice the mythlogserver instances are running as different users--daniel and mythtv |
| [15:09:21] | sphery: | this is what causes the permissions problems |
| [15:09:30] | sphery: | which is what causes mythlogserver to lock up |
| [15:09:38] | sphery: | which is what causes apps to spawn new ones |
| [15:09:47] | sphery: | which is what causes things to break |
| [15:10:17] | ubuntuaddicted: | sphery, ok but how do I fix. i didn't do anything but enable mythbuntu repository and install 0.26+fixes |
| [15:10:49] | sphery: | I have no idea how your distro has things set up |
| [15:10:58] | sphery: | but the short answer is, "only run mythtv applications as user mythtv" |
| [15:11:37] | ubuntuaddicted: | sphery, makes sense too bad I don't know how to fix that |
| [15:11:43] | sphery: | nor do I |
| [15:12:00] | sphery: | note that it seems to be a common problem--based on the number of people posting about "too many mythlogserver processes" |
| [15:12:01] | ubuntuaddicted: | my server is also locked up again, i can't even do anything in my ssh session |
| [15:12:20] | sphery: | sowell, 96.3% I/O wait will do that :) |
| [15:12:33] | sphery: | (probably around 100% by now, though) |
| [15:13:02] | ubuntuaddicted: | once it unlocks, shall I killall mythlogserver? |

| [15:14:46] | sphery: | and then /make sure/ you've killed them all (even those running as different user) |
| [15:15:40] | sphery: | anyway, no idea how something is getting run as daniel |
| [15:15:49] | ubuntuaddicted: | ok, it unfroze for a second and I issued sudo killall mythlogserver |
| [15:15:49] | sphery: | likely some wrapper script is broken or something |

| [15:16:17] | sphery: | you may need to killall mythpreviewgen, too |
| [15:16:24] | ubuntuaddicted: | but the sudo killall mythlogserver command hasn't completed yet, im waiting for it to ask for my password |
| [15:16:30] | ubuntuaddicted: | yeap, i will |
| [15:16:33] | sphery: | otherwise, it's possible that different ones will spawn new mythlogserver instances |
| [15:16:40] | sphery: | and you may end up stuck, again |
| [15:17:33] | ubuntuaddicted: | sphery, should I issue sudo service mythtv-backend stop |
| [15:17:36] | sphery: | basically, though, it's fragile on any system that's not perfectly configured or that does things that aren't supported (running apps as different users, where permissions differ between the users, possibly resulting in mythlogserver being unable to write logs it's told to write) |
| [15:17:48] | sphery: | in theory, mythbackend won't be a problem--it's only one process |
| [15:17:55] | sphery: | so if it starts mythlogserver, there's only one |
| [15:18:11] | sphery: | just kill mythlogserver and mythpreviewgen |
| [15:18:15] | ubuntuaddicted: | right but isn't the mythbackend service controlling if mythlogserver spawns or not |
| [15:18:19] | sphery: | see if that cleans it up |
| [15:18:32] | ubuntuaddicted: | ok, the sudo killall mythlogserver is still just sitting there |
| [15:18:37] | sphery: | any mythtv application that attempts to do logging will spawn a mythlogserver if one isn't available |
| [15:19:05] | sphery: | but if mythbackend spawns one, it will be available for 100 mythpreviewgen instances, too |
| [15:19:22] | sphery: | yeah, with the i/o wait, it's going to take some time |
| [15:19:45] | sphery: | especially if your low available memory means that it's swapping to disk |
| [15:19:58] | tgm4883: | sphery, does mythfrontend spawn a mythlogserver process? |
| [15:20:07] | sphery: | anyway, someone in here went and fixed his *buntu system to always run as the same user |
| [15:20:08] | devinheitmueller (devinheitmueller!~devinheit@pool-74-108-14-79.nycmny.fios.verizon.net) has quit (Quit: devinheitmueller) | |
| [15:20:22] | sphery: | I don't remember who it was, but he reworked things for a bit |
| [15:20:36] | sphery: | tgm4883: any mythtv application that attempts to log will spawn a new mythlogserver |
| [15:20:41] | sphery: | if one isn't available |
| [15:21:00] | ubuntuaddicted: | such a shame, i thought mythbuntu was my easiest option |
| [15:21:15] | ubuntuaddicted: | it's not like i did anything special or out of the originary |
| [15:21:19] | sphery: | tgm4883: I'm hoping to add a new mythtvd--though I don't know if I can get it approved before 0.27--that would be responsible for starting all the daemon processes for MythTV |
| [15:21:20] | ubuntuaddicted: | *ordinary |
| [15:21:44] | tgm4883: | sphery, if mythlogserver is running as a different user, will the frontend spawn a new one? |
| [15:22:41] | sphery: | so it would start mythlogserver, then (if configured as a backend) mythbackend, else ((if configured as a job queue, mythjobqueue) and (if configured as a streaming server, mythmediaserver)) and so on |
| [15:23:36] | ubuntuaddicted: | ubuntuaddicted, needs coffee |
| [15:23:39] | tgm4883: | sphery, so on a standard mythbuntu FE+BE install, the BE runs as user 'mythtv', the frontend runs as the user that was setup during install (explicitely not 'mythtv') |
| [15:23:45] | sphery: | tgm4883: if mythlogserver is running as a different user, the problem is generally that the differing permissions will prevent that mythlogserver from doing its job, so it will "lock up", which means it doesn't respond, so applications that attempt to log will start a new mythlogserver |
| [15:24:22] | tgm4883: | both users should be in the mythtv group though |
| [15:24:26] | sphery: | ubuntuaddicted: mythbuntu is definitely the easiest option |
| [15:24:34] | sphery: | ubuntuaddicted: it's generally worse for other distros |
| [15:24:51] | tgm4883: | which should have write permissions |
| [15:25:09] | sphery: | are you guys only doing syslog logging? |
| [15:25:15] | tgm4883: | yea |
| [15:25:26] | sphery: | if so, in theory, write permissions on log files shouldn't come into play |
| [15:25:31] | sphery: | but maybe something else is for syslog |
| [15:25:40] | tgm4883: | hmm |
| [15:26:12] | sphery: | some kind of rate limit or ??? |
| [15:26:32] | tgm4883: | so mythlogserver runs as 'mythtv' when spawned from the BE, then the FE sends logs to that mythlogserver (which in turn writes it to rsyslog, which then writes it to the log file)? |
| [15:27:02] | sphery: | right |
| [15:27:15] | tgm4883: | sphery, hmm, what happens if the system is too slow to write logs & video to disk? |
| [15:27:49] | sphery: | but then mythbackend finishes startup and doesn't need to write any log messages for a while, and since no one is using mythfrontend, it doesn't write any logs, so after 5 minutes, mythlogserver shuts down |
| [15:28:09] | sphery: | then mythfrontend writes a message and there's no mythlogserver, so it starts one |
| [15:28:20] | sphery: | then mythlogserver shuts itself down |
| [15:28:37] | sphery: | then a mythpreviewgen starts from the backend and needs a mythlogserver, so... |
| [15:28:49] | sphery: | which is why I want to simplify it to: mythlogserver never shuts down |
| [15:29:15] | sphery: | but, so that distros/users don't have to learn which daemons to start, mythtvd starts the right ones for the system for them |
| [15:29:20] | sphery: | and shuts them down for them |
| [15:29:27] | sphery: | at service shut down |
| [15:29:29] | tgm4883: | yea that makes sense to me |
| [15:29:42] | Sharky-Sleep is now known as Sharky112065 | |
| [15:29:49] | tgm4883: | sphery, does mythlogserver register anywhere with mythtv? What if we started it manually, would it be used? |
| [15:30:11] | ** tgm4883 doesn't have any combined FE+BE systems ** | |
| [15:30:13] | sphery: | it's possible that I/O wait could be causing a mythlogserver to hang long enough that a process (like one of the many mythpreviewgens that's running) times out waiting and starts a new one |
| [15:30:36] | sphery: | no, mythtv apps look for it |
| [15:30:42] | sphery: | if you start it, it would be used |
| [15:30:47] | sphery: | but it woudl stop itself after 5 min |
| [15:30:56] | tgm4883: | hmm |
| [15:30:59] | sphery: | and with upstart's "auto-restart", it would probably cause as many/more problems |
| [15:31:06] | sphery: | which is why it needs simplified |
| [15:31:36] | sphery: | I just finished up a work project, so I should have some time to work on mythtv in the next couple of weeks, so I'll see about getting a mythtvd working |
| [15:31:42] | sphery: | and see if I can get permission to put it in for 0.27 |
| [15:31:49] | tgm4883: | sphery, multiple mythlogservers are always an issue right? |
| [15:32:06] | tgm4883: | eg. never a good reason for it? |
| [15:32:12] | sphery: | tgm4883: which rsyslog do you guys use (version)? |
| [15:32:22] | sphery: | tgm4883: yes, multiple mythlogservers are always bad |
| [15:32:43] | tgm4883: | sphery, looks like 5.8 http://packages.ubuntu.com/search?keywords=rs . . . ;section=all |

| [15:33:03] | tgm4883: | sphery, so minimally, could mythlogserver check to see if it's running before starting? |
| [15:33:13] | tgm4883: | or would it just make more sense to do mythtvd |
| [15:33:16] | sphery: | it's possible that the loose "restart if I don't see it" without a controller approach causes races, but if so, that should only be 2 getting started every once in a blue moon |
| [15:33:29] | sphery: | versus the 10s of them that happen frequently/constantly on some users systems |
| [15:34:35] | sphery: | jarle: Was it you who had fixed up your *buntu system so that you didn't have problems with multiple mythlogserver instances? |

| [15:41:35] | tgm4883: | sphery, ok |
| [15:41:50] | tgm4883: | ubuntuaddicted, if they were, I think it would work a lot better than it does |
| [15:42:17] | ubuntuaddicted: | lol |
| [15:42:25] | sphery: | tgm4883: also, it seems that rsyslog 5.7.1 and above has some sort of rate limiting, which may be causing problems |
| [15:42:28] | ubuntuaddicted: | ok, the command to killall finally ended |
| [15:42:30] | sphery: | http://www.rsyslog.com/how-to-use-rate-limiting-in-rsyslog/ |
| [15:42:33] | tgm4883: | hmm |
| [15:42:45] | Jordack (Jordack!~jordack@h69-131-44-221.plmomi.dedicated.static.tds.net) has joined #mythtv-users | |
| [15:42:55] | ubuntuaddicted: | i am trying to run top but it's just sitting there again |
| [15:43:14] | tgm4883: | sphery, "By default, rate limiting will only work, if a process sends more than 200 messages in 5 seconds" |
| [15:43:30] | tgm4883: | sphery, so debug logs might do that |
| [15:43:30] | sphery: | ubuntuaddicted: it's more precise to say that the cmyth guys have decided it's not worth their time to properly support the protocol used to communicate with mythtv, so what happens when you use it is your problem, not MythTV's |
| [15:43:35] | ubuntuaddicted: | ok, i killed mythlogserver and mythpreviewgen. now what to check? |
| [15:43:51] | sphery: | (i.e. it could even cause data corruption or other issues) |
| [15:44:03] | sphery: | tgm4883: but remember that the only process sending syslog messages, now, is mythlogserver |
| [15:44:19] | sphery: | tgm4883: and it's sending them for mythbackend, mythfrontend, 10+ instances of mythpreviewgen, mythtranscode, ... |
| [15:44:26] | tgm4883: | sphery, ah true |
| [15:44:32] | sphery: | so I'd think we could hit 200 messages in 5s rather easily |
| [15:44:52] | sphery: | especially with all the "startup garbage" in the logs (giving version and environment info) that we need to debug problems |
| [15:45:22] | tgm4883: | sphery, I'd don't recall seeing this though when I was logging on my backend only |
| [15:45:30] | sphery: | and might explain why it only seems to hit some users--those who run single, combined frontend/backend systems |
| [15:45:37] | tgm4883: | hmm ok |
| [15:45:58] | sphery: | yeah, might not be relevant, but worth checking |
| [15:46:00] | tgm4883: | yea I probably only run mythbackend and mythmedialookup on that system |
| [15:46:06] | sphery: | to see if it's enabled |
| [15:46:12] | tgm4883: | sphery, yea, lets see if we can disable it |
| [15:46:29] | sphery: | not even sure what it does if you exceed the limit--throws away messages or blocks additional writes or ... |
| [15:46:37] | ubuntuaddicted: | ok, they keep respawning |
| [15:46:45] | sphery: | Oct 5 18:23:52 client rsyslogd-2177: imuxsock begins to drop messages from pid 7200 due to rate-limiting |
| [15:46:52] | sphery: | seems that it just drops them |
| [15:47:15] | tgm4883: | sphery, so that shouldn't be blocking then (although we'll want to fix that since we wouldn't be getting full logs) |
| [15:47:18] | sphery: | right |
| [15:47:35] | ubuntuaddicted: | what should I check? |
| [15:47:40] | sphery: | and whether to "fix" it or not is up to you |
| [15:48:04] | tgm4883: | sphery, I'd be more comfortable setting that to a good default rather then disabling it completely (although if you guys figure out logging to DB then it's a moot point) |
| [15:48:08] | sphery: | we might be able to fix it better by rearchitecting things a bit |
| [15:48:27] | sphery: | so that you can have the limit for "it's getting crazy" while still getting sufficient info |
| [15:48:36] | tgm4883: | sphery, nah, I say get logging to DB working then we can disable logging to file completely |
| [15:48:40] | ** tgm4883 doesn't log at all right now ** | |
| [15:48:43] | sphery: | what do you mean "figure out logging to db"? |
| [15:48:59] | sphery: | ttbomk it works fine |
| [15:49:07] | tgm4883: | sphery, last I checked, wagn errp was writting a tool to pull logs from there, but it doesn't pull full timestamps |
| [15:49:14] | tgm4883: | IIRC, it's only down to the second |
| [15:49:24] | ubuntuaddicted: | ok, mythlogserver spawned again |
| [15:49:27] | sphery: | right, because mysql doesn't store more |
| [15:49:32] | sphery: | but logging is in there |
| [15:49:48] | sphery: | and the proper tool for pulling logging out of the db is the service api method for it |
| [15:49:51] | tgm4883: | sphery, ah, so you'd have to change the column type? |
| [15:50:04] | sphery: | which, fwiw, I hope to get wagnerrp to switch his tool to use |
| [15:50:39] | ubuntuaddicted: | sphery, not sure what to do next |
| [15:51:25] | sphery: | tgm4883: we may just change it to store the epoch timestamp in one field and a nano int in another |
| [15:51:35] | tgm4883: | sphery, yea that would be a good solution. I don't like to duplicate what wagnerrp does |

| [15:54:33] | ubuntuaddicted: | sphery, i see this in the mythpreviewgen.log file mythlogserver: mythpreviewgen[5176]: E CoreContext mythdbcon.cpp:217 (OpenDatabase) Driver error was [1/1129]:#012QMYSQL: Unable to connect#012Database error was:#012Host 'dell.local' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts' |
| [15:54:35] | sphery: | is he only logging to syslog? |
| [15:54:40] | sphery: | and it logging to file? |
| [15:54:57] | sphery: | if so, no idea why mythlogservers are "locking up" |
| [15:55:03] | sphery: | but it's worth a try |
| [15:55:18] | tgm4883: | sphery, well he logs to syslog, and that goes to file |
| [15:55:21] | ubuntuaddicted: | sphery, i see this as well: mythlogserver: mythpreviewgen[5176]: E CoreContext mythdbcon.cpp:216 (OpenDatabase) Unable to connect to database! |
| [15:55:26] | tgm4883: | sphery, "LANG=$LANG exec /usr/bin/mythbackend --syslog local7 --user mythtv" |
| [15:55:31] | sphery: | ubuntuaddicted: it seems that the mysql configuration is your problem |
| [15:55:35] | tgm4883: | sphery, that is how we start mythbackend |
| [15:55:37] | sphery: | 012QMYSQL: Unable to connect#012Database error was:#012Host 'dell.local' is blocked because of many connection errors; unblock with 'mysqladmin flush-hosts' |
| [15:55:46] | sphery: | and that would affect mythlogserver, too |
| [15:56:03] | sphery: | and, again, connection errors occur because of invalid config.xml |
| [15:56:04] | ubuntuaddicted: | sphery, ok, where do I start to troubleshoot |
| [15:56:09] | sphery: | so fine /every single one/ on your system and fix it |
| [15:56:20] | sphery: | you have some garbage/broken ones in there |
| [15:56:26] | tgm4883: | ubuntuaddicted, check /home/mythtv/.mythtv/config.xml |
| [15:56:33] | sphery: | tgm4883: why not --daemon ? |
| [15:56:43] | sphery: | tgm4883: with the above, you're doing console logging |
| [15:57:01] | sphery: | which is then going to whatever stdout/stderr was set up |
| [15:57:05] | tgm4883: | hmm |
| [15:57:10] | sphery: | and might be intercepted by something else and written to ??? |
| [15:57:19] | tgm4883: | sphery, let me check my backend |
| [15:58:01] | sphery: | ubuntuaddicted: may want to do a locale config.xml , too, to find if there are others elsewhere |
| [15:58:08] | sphery: | er, locate config.xml |
| [15:58:16] | ** sphery types locale way too often ** | |
| [15:58:23] | ubuntuaddicted: | sphery, cat /home/mythtv/.mythtv/config.xml is fine |
| [15:59:04] | ubuntuaddicted: | sphery, cat /home/daniel/.mythtv/config.xml is fine as well |
| [15:59:06] | tgm4883: | sphery, is that error a mysql security feature? |
| [15:59:15] | sphery: | tgm4883: seems to be |
| [15:59:18] | tgm4883: | sphery, eg. it blocked a host after too many connection failures |
| [15:59:22] | tgm4883: | but he's fixed the failures |
| [15:59:27] | tgm4883: | but not unblocked it yet? |
| [15:59:51] | sphery: | fixed the failures? |
| [15:59:53] | ubuntuaddicted: | tgm4883, how do I unblock it? |
| [16:00:00] | sphery: | ubuntuaddicted: mysqladmin flush-hosts |
| [16:00:11] | tgm4883: | sphery, well he previously had an incorrect config.xml file |
| [16:00:16] | tgm4883: | sphery, we fixed that yesterday |
| [16:00:21] | sphery: | http://dev.mysql.com/doc/refman/5.0/en/blocked-host.html |
| [16:00:27] | ubuntuaddicted: | tgm4883, mysqladmin: connect to server at 'localhost' failed |
| [16:00:38] | sphery: | "interrupted connection requests"... ??? |
| [16:01:00] | ubuntuaddicted: | sphery, adding sudo returns this error: 'Access denied for user 'root'@'localhost' (using password: NO)' |
| [16:01:03] | tgm4883: | ubuntuaddicted, I assume you need some sort of credential switches |
| [16:01:17] | sphery: | yeah, likely a -uroot -p |
| [16:01:39] | sphery: | mysqladmin -uroot -p flush-hosts |
| [16:01:49] | sphery: | no clue what your MySQL root password is, though |
| [16:01:56] | ubuntuaddicted: | sphery, i tried sudo mysqladmin -uroot -p flush-hosts |
| [16:01:57] | tgm4883: | and the password I believe is the default users password |
| [16:02:02] | ubuntuaddicted: | but the root password I tried isn't working |
| [16:02:04] | tgm4883: | so in this case, daniel's password |
| [16:02:08] | sphery: | "If you are having network problems, it does you no good to increase the value of the max_connect_errors variable." |
| [16:02:27] | sphery: | i.e. it sounds like this can be caused not only by bad login info, but also by network errors while communicating |
| [16:02:28] | hashbang (hashbang!~isajb@cse-ajb.cse.bris.ac.uk) has quit (Quit: Leaving.) | |
| [16:02:47] | sphery: | and that would likely cause all sorts of problems, and may explain all of the symptons you're seeing |
| [16:02:52] | ubuntuaddicted: | sphery, how can I reset the root password |
| [16:03:06] | tgm4883: | it would appear that I forgot the knock sequence to my backend :( |
| [16:03:07] | ubuntuaddicted: | sphery, i used to know it before I upgraded to 0.26+fixes |
| [16:03:09] | sphery: | did you use daniel's password? |
| [16:03:13] | ubuntuaddicted: | sphery, yes |
| [16:03:27] | tgm4883: | sudo dpkg-reconfigure mysql-server-5.5 |
| [16:03:32] | sphery: | tgm4883 would know how to properly reset mysql root password on *buntu |
| [16:03:58] | sphery: | and it seems he was faster at typing the howto than I was at typing the referral to him |
| [16:04:23] | tgm4883: | sphery, c&p, we have a bot that has that info |
| [16:05:15] | ubuntuaddicted: | sphery, ok, trying now |

| [16:08:13] | ubuntuaddicted: | sphery, ok, i flushed the hosts using sudo mysqladmin -uroot -p flush-hosts |
| [16:08:28] | ubuntuaddicted: | sphery, ok, what should I check next? |
| [16:08:30] | sphery: | could be anything from network issues (failing hardware or bad cabling or ...) to configuration problems |
| [16:08:38] | sphery: | no clue where to start |
| [16:08:49] | sphery: | is everything on a single system? |
| [16:09:14] | ubuntuaddicted: | sphery, i noticed that /usr/share/mythtv/config.xml was wrong, i have just fixed it |
| [16:09:25] | ubuntuaddicted: | sphery, yes |
| [16:09:27] | sphery: | ok, that may be what was causing it, then |
| [16:09:46] | ubuntuaddicted: | sphery, do I need to update this file? /usr/share/doc/mythtv-backend/contrib/config_files/config.xml |
| [16:09:49] | sphery: | in which case it's not likely to be network (as it's all "inside the box") |
| [16:09:58] | sphery: | so the bad config.xml is likely the problem |
| [16:10:07] | sphery: | the one in doc /shouldn't/ be used by anything |

| [16:10:46] | sphery: | tgm4883: is he even supposed to have a /usr/share/mythtv/config.xml ? If not, perhaps he should delete it? |
| [16:11:00] | tgm4883: | sphery, IDK, it shouldn't be getting used |
| [16:11:01] | ubuntuaddicted: | sphery, but they are named like bbc_config.xml and stuff like that |
| [16:11:28] | sphery: | those are different |
| [16:11:36] | sphery: | so ignore the internetcontent ones |
| [16:12:19] | sphery: | anyway, I have to get some stuff done, today, so I'll leave you with my fingers crossed |
| [16:12:23] | sphery: | hope that helps |
| [16:12:36] | ubuntuaddicted: | sphery, so just restart the backend? |
| [16:12:47] | sphery: | but that's the biggest problem with MythTV--it requires a /lot/ of system things to be working before it will work |

| [16:31:50] | tgm4883: | ubuntuaddicted, sphery it looks to me that there is an issue with mythpreviewgen |
| [16:32:09] | ubuntuaddicted: | tgm4883, before I fixed the /usr/share/mythtv/config.xml |
| [16:32:23] | tgm4883: | ubuntuaddicted, I'm not going to worry about that error unless we see a new one |
| [16:33:37] | ubuntuaddicted: | tgm4883, well, here's a new TOP. https://lh5.googleusercontent.com/-5Klqan5iHA . . . 0%2520AM.png |
| [16:34:21] | ubuntuaddicted: | tgm4883, i've tried to delete 2 recordings from mythweb |
| [16:34:45] | sphery: | ubuntuaddicted: it's spawning mythpreviewgens to create previews for you |
| [16:34:48] | sphery: | that's normal |
| [16:34:54] | ubuntuaddicted: | tgm4883, and mythweb just says at the bottom left "2 requests pending" |
| [16:34:59] | sphery: | only multiple mythlogservers is abnormal |
| [16:35:01] | tgm4883: | sphery, so multiple mythpreviewgens is normal? |
| [16:35:40] | tgm4883: | how is load 20 if none of that is taking CPU? |
| [16:35:58] | sphery: | load is a measure of how many things want to use the cpu |
| [16:36:02] | ubuntuaddicted: | sphery, tgm4883 i need to figure out this mythpreviewgen problem I am having, any thoughts? |
| [16:36:14] | sphery: | but they may not be able to use it now if they're stuck in i/o wait or something |
| [16:36:34] | tgm4883: | sphery, yea, it's all wait it seems |
| [16:36:40] | sphery: | it's looking like mysql issues |
| [16:36:40] | tgm4883: | 95.9% |
| [16:36:51] | sphery: | Driver error was [1/2003]:#012QMYSQL: Unable to connect#012Database error was:#012Can't connect to MySQL server on '192.168.0.5' (111) |
| [16:37:10] | ubuntuaddicted: | here's the last bit from the backend log http://pastebin.com/ZgaMReeu |
| [16:37:15] | tgm4883: | sphery, should we just reset all mysql credentials? |
| [16:37:16] | sphery: | ubuntuaddicted: if your mysql server is on the same host as your backend, you should change the DBHostName to 127.0.0.1 |
| [16:37:41] | sphery: | that way you'll use the *significantly* more-efficent UNIX socket connection rather than a TCP/IP connection on the same host |
| [16:38:02] | tgm4883: | sphery, +1, lets move to 127.0.0.1 at least as a test |
| [16:38:04] | sphery: | note that you can only do that on exactly one machine in your MythTV system--the one that's also hosting the MySQL server |
| [16:38:16] | ubuntuaddicted: | sphery, the mysql server is on the same host. so change all the config.xml files to 127.0.0.1? |
| [16:38:35] | sphery: | yes, but /only/ for the dbhostname |
| [16:38:59] | ubuntuaddicted: | sphery, so all the config.xml files on the backend host should be dbhostname 127.0.0.1? |
| [16:39:13] | sphery: | yep |
| [16:39:17] | ubuntuaddicted: | sphery, ok |
| [16:39:26] | ubuntuaddicted: | sphery, should I stop the mythbackend? |
| [16:39:35] | sphery: | and note that that is the /only/ place in a mythtv system where you should use 127.0.0.1 or localhost |
| [16:39:47] | sphery: | never use it for your backend IP addresses |
| [16:39:56] | sphery: | and, yeah, you'll need to stop and restart |
| [16:40:04] | sphery: | but kill your previewgens, then logservers |
| [16:40:05] | sphery: | first |
| [16:40:07] | sphery: | and last |
| [16:40:15] | sphery: | then when no mythtv apps are running, start mythbackend |
| [16:41:11] | ubuntuaddicted: | sphery, what about the mysql.txt or my.cnf? |
| [16:42:00] | sphery: | you shouldn't have any mysql.txt in mythtv 0.26 and above |
| [16:42:33] | sphery: | and my.cnf is a mysql configuration file, unrelated to mythtv (though it can have some impact on some things, like mythconverg_backup.pl) |
| [16:43:12] | ubuntuaddicted: | this is the last bit from mythbackend.log http://pastebin.com/ZgaMReeu |
| [16:44:27] | sphery: | ubuntuaddicted: while you have mythtv apps shut down, clear the log files so you don't get confused by old messages |
| [16:44:51] | ubuntuaddicted: | sphery, trying to get the mythpreviewgen and mythlogserver killed. |

| [17:59:41] | sphery: | mythlogserver would consume a ton of time when you have multiple mythlogservers because some (most?/all but one?) of them would be spinning |
| [17:59:56] | sphery: | which is why you should configure your system properly so that doesn't happen |
| [17:59:59] | tgm4883: | sphery, this thing as a lot of issues |
| [18:00:03] | sphery: | hard part is figuring out what's causing it though |
| [18:00:24] | tgm4883: | sphery, he's configured mysql to only listen on the external ip address |
| [18:00:32] | tgm4883: | so IDK if 127.0.0.1 is even working |
| [18:00:51] | sphery: | 127.0.0.1 gets changed so it doesn't use TCP/IP |
| [18:00:54] | sphery: | it will use Unix sockets |
| [18:01:10] | tgm4883: | I think it's to a point where he's googled and done enough damage that he needs to wipe the box and start again |
| [18:01:17] | sphery: | +1 |
| [18:01:23] | tgm4883: | and possibly buy a better backend |
| [18:01:40] | sphery: | and, having read some of the backlog, you guys made me realize just how little memory he's trying to use |
| [18:01:45] | sphery: | it may just be asking too much |
| [18:02:07] | tgm4883: | yea, he's in what we'd call an unsupported configuration |
| [18:02:19] | sphery: | when he said "256 MB", I read "small amount of memory", but I didn't realize just how small until someone mentioned, "most use GBs of RAM" |
| [18:02:41] | tgm4883: | he's got half the ram we require and has disabled X (in an attempt to use little ram) |
| [18:02:50] | sphery: | it's sad that I remember when 256MB was a modest system |
| [18:03:00] | sphery: | yeah |
| [18:03:08] | sphery: | may just be asking too much of the system |
| [18:03:25] | tgm4883: | again, I think it's an issue with the age of the machine, but if he wants to try a fresh install+restore DB, I think it's worth a shot |
| [18:03:29] | sphery: | after all, if you want a high-end, luxury DVR, you need a system that can support it |
| [18:03:49] | tgm4883: | but I've been searching, and I've found a few of his posts around the web that suggest he's done some weird thigns |
| [18:04:05] | tgm4883: | I think he knows just enough to get him into trouble |
| [18:04:24] | tgm4883: | (just enough being "I can edit system files and restart services) |
| [18:04:28] | sphery: | hehe, as do too many of us |
| [18:04:55] | tgm4883: | sphery, you guys don't mark bitesized bugs do you? |
| [18:05:07] | sphery: | (meaning that few of us fully comprehend the effects of changes we make--and, especially, the interconnected nature of the effects of those changes on other parts of the systems) |
| [18:05:18] | tgm4883: | I'd hate to just grab one to look at and it be this massive cluster-f to work out |
| [18:05:21] | sphery: | hehe, for a while I think they were trying to |
| [18:05:24] | sphery: | I don't remember how |
| [18:05:56] | tgm4883: | sphery, I'd be surprised if anyone knew exactly how mythtv actually worked |
| [18:06:02] | sphery: | I have to go see if the power outage borked one of my systems... it's saying I'm not authorized when I try to ssh in |
| [18:06:36] | tgm4883: | sphery, as much outdated as it was, at my previous job there was a diagram of what parts of the software talked to other parts of the software |
| [18:06:43] | sphery: | guess I'm going to need a keyboard for that |
| [18:06:54] | sphery: | cool |
| [18:07:06] | tgm4883: | sphery, also, thanks for the heads up on the daemon stuff. We'll be adding that |
| [18:07:13] | sphery: | mythtv is especially hard because there's so much internal and external dependencies |
| [18:07:20] | tgm4883: | sphery, by default, we log the exact same info to 3 places |
| [18:07:43] | tgm4883: | sphery, maybe I'll try to diagram it |
| [18:10:07] | sphery: | cool, yeah, sounds like switching to --daemon help a bit |
| [18:10:21] | tgm4883: | sphery, yep, that will remove one of the places we log |
| [18:10:32] | tgm4883: | sphery, I'm trying to decide if we need to log to syslog AND the DB |
| [18:10:41] | sphery: | especially for users who change default logging "just in case of problems" (and have been causing problems with the excessive i/o requirements from overly-verbose logging) |
| [18:11:06] | joelsplace: | I remember when 4MB was way overkill. |
| [18:11:07] | sphery: | the main reasoning for db logging is to allow users to view logs of any app from any machine |
| [18:11:29] | sphery: | the main problem with that is that we don't have a good viewer application, yet |
| [18:11:49] | sphery: | though we do have the log viewer service, you'd have to transform the xml to make it human-readable |
| [18:11:50] | tgm4883: | sphery, once there is a good viewer, perhaps we should default to no syslog logging |
| [18:12:03] | sphery: | well, the db logging is only "short-term" logging, too |
| [18:12:14] | tgm4883: | sphery, 2 weeks |
| [18:12:16] | sphery: | max of 2 weeks, IIRC, or 40K entries? |
| [18:12:25] | tgm4883: | sphery, I'm not too worried about going back 2 weeks worth |
| [18:12:29] | tgm4883: | at least as a default |
| [18:12:36] | sphery: | how did I lose my .k5login... |
| [18:13:05] | sphery: | ah, wait, I didn't |

| [19:26:54] | yahya69: | sphery: if mythtv had been compiled incorrectly, shouldn't it then fail entirely (not just the archiving) |
| [19:26:58] | yahya69: | ? |
| [19:27:23] | sphery: | no, generally it means that you're running it on a related, but not 100% compatible architecture |
| [19:28:07] | sphery: | i.e. it was compiled for a system with sse3 and your system only supports sse2, so when you hit an sse3 instruction.... boom |

| [19:34:57] | sphery: | what is "archive function"? |
| [19:34:59] | sphery: | mytharchive? |
| [19:35:03] | yahya69: | sphery: yes |

| [19:35:16] | yahya69: | sphery: no, mytharchive |
| [19:35:17] | sphery: | if mytharchive, I'm pretty sure it's just a bunch of scripts calling external programs |
| [19:35:24] | sphery: | one of which is likely failing/improperly compiled |
| [19:35:46] | sphery: | or, if you haven't verified the command line--it's just exiting because your command line is wrong |
| [19:35:57] | yahya69: | sphery: according to the log, it calls mythutil, which then fails |
| [19:36:20] | yahya69: | sphery: I have checked the command line, and there I get the following result: |

| [19:38:40] | sphery: | no idea, then |
| [19:38:46] | Gumby`: | hi all. is this howto still valid for moving recordings to another box http://www.mythpvr.com/mythtv/tips/migrate-recordings.html |
| [19:38:54] | sphery: | Gumby`: no, it /never/ was valid |
| [19:39:06] | sphery: | and google should be shot for showing it to so many people |
| [19:39:09] | sphery: | it corrupts your database |
| [19:39:16] | bill6502: | yahya69: since this started happening recently, is there plenty of space in /tmp? |
| [19:39:22] | Gumby`: | hrm, ok then. is there a "proper" or recommended way of doing it then? |
| [19:40:24] | yahya69: | sphery: so I should probably file a bug, however is it rather a mythtv bug or a Debian bug? There are 7.3 Gbyte free in /tmp. Should be enough to archive an episode of one GByte I would hope |
| [19:40:31] | sphery: | Gumby`: all there is to moving recordings to a new backend is: install new backend, restore a /full/ database backup ( http://www.mythtv.org/wiki/Database_Backup_an . . . ing_database ), and--assuming you were smart and used the same host name for the new machine--start mythtv-setup to upgrade the database/change settings (such as Storage Groups) |
| [19:40:41] | sphery: | i.e. there is no such thing as "migrating" recordings |
| [19:41:12] | sphery: | yahya69: if it's an illegal instruction, it's not mythtv bug |

| [19:41:52] | sphery: | yahya69: if mytharchive doesn't use mythtv's standard exit codes, it may be some other problem it's trying to inform you about, but I have no idea what it is |
| [19:42:03] | sphery: | Gumby`: there's absolutely no benefit to starting a new DB |
| [19:42:12] | sphery: | the only thing it will do is force you to reconfigure everything |
| [19:42:23] | Gumby`: | isnt that the fun part though ;) |
| [19:42:24] | sphery: | if you really want to do that, just go through settings |
| [19:42:36] | sphery: | http://www.mythtv.org/wiki/Database_Backup_an . . . _of_a_backup explains why it's not useful |
| [19:42:48] | Gumby`: | cool, I'll have a read. Thanks |
| [19:43:12] | sphery: | in the end--IF you reconfigure properly--you've wasted tons of time and gotten /exactly/ what you would have had if you just simply used the full database backup |
| [19:43:24] | sphery: | but you'll have to recreate /everything/ if you try to do a partial restore |
| [19:43:31] | sphery: | and it won't affect performance or anything |
| [19:44:10] | sphery: | will just waste hours of your life (that could better be spent reading and suggesting edits for the HOWTO at http://www.mythtv.org/wiki/MythTV-HOWTO , or working on improving a MythTV theme, or working on code for MythTV or ... :) |
| [19:44:42] | sphery: | and by "everything", I mean everything--settings, configuration, plugin data (all of it--including metadata, etc.) |
| [19:44:59] | sphery: | the only reason for a partial restore is if you have a corrupt schema or corrupt data |
| [19:45:10] | sphery: | so if your mythtv has generally been working properly, just use the full DB |

| [20:12:53] | ubuntuaddicted: | sphery, im back :) a million mythlogserver and mythpreviewgen have brought my server to it's knees |
| [20:14:35] | sphery: | ubuntuaddicted: it's possible that your system just isn't powerful enough to handle mythtv |
| [20:15:06] | sphery: | and mythlogserver takes too long to respond when something checks if it's there, so that something starts a new one |
| [20:15:18] | sphery: | which just makes thing worse for your system |
| [20:15:35] | sphery: | mythtv is a high-end luxury dvr, so you can't just throw ancient hardware at it |
| [20:15:57] | sphery: | (it's since dawned on me just how ancient a 256MB system would be) |

| [20:17:36] | ubuntuaddicted: | sphery, mythtv has changed so much since 0.23+fixes cause that used to work just fine |
| [20:18:00] | sphery: | ubuntuaddicted: let's just say I have no idea what's wrong |
| [20:18:34] | sphery: | but at this point, I'd have given up and just created a database backup, installed mythbuntu from scratch (no upgrades or anything), and restored the database on that new install |
| [20:18:46] | sphery: | and if that didn't work, would probably wait for a more-powerful system |
| [20:18:52] | ubuntuaddicted: | sphery, it sucks, cause I was dreading the day i upgraded my backend and my worst fears came true |
| [20:19:48] | ubuntuaddicted: | sphery, yeah, the system was working with mythbuntu 12.04 and 0.25+fixes just fine expect for black thumbnails |
| [20:19:57] | sphery: | the worst part is that the time you've spent on the "upgrade so I don't have to do a full install" is probably much greater than the time it would have taken to do a full install |
| [20:20:13] | ubuntuaddicted: | sphery, i did a full install |
| [20:20:17] | ubuntuaddicted: | sphery, new install |
| [20:20:52] | sphery: | well, something is very messed up outside of mythtv |
| [20:20:53] | ubuntuaddicted: | sphery, i installed mythbuntu 12.04.2 from scratch and restored my database. |
| [20:20:56] | sphery: | since mythtv can't talk with the database |
| [20:21:12] | sphery: | but I don't know what's happening |
| [20:21:28] | ubuntuaddicted: | sphery, ok, im going to get the new hardware and go from there. |
| [20:21:29] | sphery: | it's possible that changes you've made in trying to fix things are contributing to the issues, now |
| [20:21:38] | ubuntuaddicted: | sphery, i appreciate your help very much |
| [20:21:43] | sphery: | but I have no idea what's wrong |
| [20:21:59] | sphery: | I can only say that my system is rock solid stable (and I hope saying that isn't tempting fate) |
| [20:22:10] | sphery: | the only issues I've had have come down to hardware issues |
| [20:22:20] | ubuntuaddicted: | sphery, whats in .26+fixes thats not in .25+fixes? |
| [20:23:24] | sphery: | on one system I maintain for a friend, it kept crashing--I thought it was thermal shutdown, so he cleaned fans and blew out dust and ..., but that didn't help, so he removed/cleaned/replaced heatsink/fans, didn't help, so he started replacing components (PSU, memory, ...), but that didn't help |
| [20:23:49] | sphery: | in the end, he took his desktop system, turned it into his mythtv system, and installed Windows on the old MythTV system for his desktop |
| [20:23:55] | sphery: | now his desktop crashes |

| [20:24:31] | sphery: | i.e. if you find issues in 0.25-fixes, I'm not going to waste time fixing them |
| [20:25:12] | ubuntuaddicted: | sphery, so if I do this again BUT upgrade to 0.26+fixes prior to doing a full restore of my database do you think I'll have any better luck? |
| [20:25:42] | ubuntuaddicted: | sphery, except for a weird issue where I had very old mythvideo tables that needed to be deleted |

| [20:28:15] | ubuntuaddicted: | sphery, is that normal even? lol |
| [20:30:45] | ubuntuaddicted: | sphery, can I shut off mythlogserver? |
| [20:30:52] | sphery: | whether you used 0.25-fixes or 0.26-fixes to do the database upgrade will make no difference |
| [20:31:18] | sphery: | I don't think any of the problem is in mythtv configuration |
| [20:31:21] | sphery: | it's all external config |
| [20:31:33] | sphery: | so feel free to use a backup of the current DB |
| [20:34:19] | ubuntuaddicted: | sphery, ok, noted. i can use the current database as is. |
| [20:34:34] | ubuntuaddicted: | sphery, how would i shut off mythlogserver? |
| [20:38:58] | ubuntuaddicted: | sphery, i can schedule recordings and look at the listings page but everytime i click on recorded programs it start mythpreviewgen and then a bunch of mythlogserver |
| [20:40:20] | sphery: | there's no supported way to shut off mythlogserver--only supported approach is to configure your system so it runs properly |
| [20:41:00] | sphery: | and the problem is likely that because you have no previews, every time you try to go to Recorded Programs you're *hammering* your system |
| [20:41:13] | sphery: | which isn't good for an ancient, underpowered system |
| [20:41:29] | ubuntuaddicted: | sphery, agreed |
| [20:41:32] | sphery: | removing all previews and then going to Recorded Programs has /always/ been a challenge for a MythTV systemn |
| [20:41:45] | sphery: | because, say you have 500 recordings--it results in spawning 500 mythpreviewgens |

| [20:42:07] | sphery: | so what you need to do is use a real^H^H^H^Hclient to create the previews at a rate that's slow enough your system can cope |
| [20:42:12] | sphery: | i.e. go to mythfrontend |
| [20:42:20] | sphery: | go into Watch Recordings |
| [20:42:23] | sphery: | don't touch MythWeb |
| [20:42:34] | sphery: | wait until every single preview on the first page shows |
| [20:42:36] | sphery: | then scroll down |
| [20:42:42] | sphery: | repeat ad nauseumn |
| [20:43:02] | ubuntuaddicted: | sphery, ok, will try that, the thing is that the preview size is different on mythfrontend then in mythweb |
