[mythtv-users] myth CVS hang

[William Lott]

Every couple of days the mythtv backend hangs on me.  I haven't been 
able to figure out what triggers it and the backend log doesn't give any 
hints.  This started happening sometime Novemberish while I was still 
running 0.16 and has persisted past switching to CVS (Jan 1 update).  If 
anyone can give me any suggestions, I'd be greatly appreciative.  I love 
my mythtv box, but not being able to rely on it has become quite 
frustrating.  And my friends who though I should just get a tivo are 
starting to snicker.

Appended is a backtrace, but I forgot to recompile with debug info so I 
don't know how useful it will be.  I'm going to start a recompile as 
soon as I send this message, but I figured I'd send this teaser out in 
case it means anything to anyone.

The machine in question is an Athlon XP 2k+, ASUS A7V8X-MX SE mobo, 512M 
ram, two Haupguage PVR 250s, and a GeForce 4 MX.  I'm running Fedora 
Core 1 setup using Jarod's guide and the latest stable ATrpms.  I'm 
using the 6106 nvidia drivers.

Thank you all,

-William Lott
