[mythtv] Backend Crash (0.18.1 + svn20050726)

Sat Jul 30 14:02:08 EDT 2005
The backend in 0.18.1 crashes once or twice a day. 0.18 crashed about
once a week. I pulled in the latest SVN earlier this week after reading
some threads on the subject, but I am still getting the crash. A stack
trace is enclosed below. Let me know what else I can provide. It is
fairly reproducible and seems to coincide the a recording finishing up.
System is a dual P3 running Debian Sarge plus whatever else I needed out
of sid to install the myth packages. I have one generic BTTV frame
grabber and a Hauppage PVR-350.
I've also had backend lockups where my video partition will reach 100%
even though I have auto-expire set to a 2GB limit checked every 10
minutes. Auto-expire does work (I have seen the logs), but sometimes it
seems that it does not and the logs fill with angry messages from an
encoder (usually audio) that it cannot write.
Thanks,
Russ
