Backend Memory Corruption Crash, 0.20

Reported by: anonymous Owned by: Isaac Richards
Priority: major Milestone: unknown
Component: mythtv Version: 0.20
Severity: medium Keywords: backend crash, memory corruption
Cc: Ticket locked: no

Description (last modified by Isaac Richards)

I have been running a very stable backend, several weeks with no crashes. And all of a sudden the backend crashes when changing channels. Running this version:

da@brutus ~ $ equery w mythtv /usr/portage/media-tv/mythtv/mythtv-0.20_p12172.ebuild

When checking through the log it seems that the recordedseek table has somehow become corrupted, but Ididn't notice this until checking the log for the reason for the crash.

The complete log-file, compressed, can be downloaded here:

How this helps and contributes for a better MythTV :-)

I forgot to say that there is a complete backtrace in the end of the log.

Use mysqlcheck to repair your database, instructions in the docs.

Ofcourse I repaired my database. That is not the point. The point is that the database was corrupted and then the backend crashed becuase of memory corruption. There is a bug somewhere. The resolution to this ticket is ofcourse not to repair the database, as the database will be corrupted again, and the backend crash again.

Reopen when you have a full backtrace, then. There is _not_ one in the rather excessive 1.2 million line log file you posted.

comment:5 Changed 13 years ago by apanloco@…

In the last 300 lines of the provided log-file you will find the following, which looks like a backtrace, but maybe not a full? (Although debugging symbols seems gone, but I can't do much about that.) If there is something else you want me to do in case it happens again, please tell. (I'll leave it as closed. Sorry to bother you.)

Right. While technically a backtrace, it's not useful for debugging at all.

I can confirm this exact behaviour but my suspicion is that this is caused by the user.... my story is almost the same... all very stable until about 2 weeks or so ago now has frequent crashes... myth complains of recordseek table being crashed and I get a "backtrace' output similar to the one posted above.... but the libraries reference are /lib64/libnss_files-2.5.so and /usr/qt/3/plugins/sqldrivers/libqsqlmysql.so.... running mysqlrepair did not find any problems in my case... in my case I PRELINKED the system recently and I am thinking that this has broken some libraries... I am running the latest SVN head on an am64 running gentoo 2.6.20-r2... I will add to this ticket if I learn something more significant....
