I think I have the same problem on my mythtv setup. I have a backend
(ubuntu 7.10 edgy) and a couple of networked frontends (ubuntu
8.04feisty). The backend will sometimes crash while watching live TV.
crashes the backend log looks a lot like what Jeff Bevis posted. I think it
happens when one program ends and another begins. I never use the "watch
live TV" function so I have never actually seen it crash. But my other
users see it happen a lot.
Jeff, Could you post your cron script that you wrote? Right now sometimes
my MythTV users will crash the backend and it will sit idle until I get home
and restart it. Having a script that will check and restart the backend
every five minuets would be great.
