Tvheadend

I am running version 3.2.34 on Linuxmint13 (ubuntu based) distribution. The machine its running on is a dedicated file/tvheadend server, and basicly runs 24/7. I have been noticing program record starting late or finishiing early. Seem to be getting more frequent too. I rebooted the box yesterday to see if that fixes it. Does anyone else run TVHeadEnd like this? If so any similar issues? Is there a log file anywhere that may possibly contain any errors?

Thanks
