[mythtv-users] Mythbackend chokes and dies once in a while

[Andrew]

Hi,

My mythbackend dies once in a while at random.  Here is the log where it chokes.  The last few lines then just repeat 
for about 140,000 lines in my log before it dies. I suspect it could be a transcode error.  Transcode and all other 
services usually work great though! Any ideas??
