[mythtv-users] Backend crashing

[Trond Nystuen]

My combined FE/BE have a problem with BE crashing. From the log:

Aug 16 21:56:05 merkur  mythbackend[5111]: I Scheduler scheduler.cpp:2140 (HandleReschedule) Reschedule requested for MATCH 0 1 6 2014-08-16T20:50:00Z EITScanner

"Minnesegmentsfeil" would be something like "Memory Segmentation Fault" in English.

The database has been used for several years. Some time ago I upgraded to 0.26 from 0.24, and then to 0.27.

I'm running Debian Wheezy, and I have compiled MythTV myself.

I have a cron job restarting the BE if it is not running, which is not very satisfying. The crash seems to occur from 1 to 4-5 times a day. Sometimes when watching live TV, or when watching recordings, I can see the connection to the BE is lost. But the crashes also happen in the night. The system is running 24/7.


A test system running a very similar configuration does not have this problem. This system had a "clean" database installed.


Any ideas?
