7.10 edgy) and a couple of networked frontends (ubuntu 8.04 feisty). The backend will sometimes crash while watching live TV. When it 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.
<br><br>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.
