I have the same setup, running Openelec 3.2.3 (official). My setup freezes after between around 20 minutes and 2 hours. I have now removed my modest overclock setting and am testing further (had an hour's freeze free viewing yesterday).

Ah, at least it's not just me then.

Mine does seem to be a lot better without the overclock, so maybe something about tvheadend or the tuner drivers is just very sensitive to overclocking. It will be a shame if we can't overclock because of this but maybe a less aggressive overclock than I had before might be OK.

Well without the overclock I haven't had any lockups but still a lot of pauses, so I can only guess that when those happen when overclocking, sometimes they cause it to crash.

I noticed one pause at around 09:56 and here's the tvheadend server.log http://xbmclogs.com/show.php?id=87180 and the xbmc.log for that time (I've included the start of the log as well) http://xbmclogs.com/show.php?id=87182

As you can see, there's continuity errors around that time but plenty of other times as well, when it didn't freeze, so maybe they accumulate and cause it to pause. At 09:56:33 there's

09:56:33 T:2524001360 DEBUG: Pause 0.09,0.89 (A:10 V:00) EOF:0 FULL:0 T:3.20

09:56:42 T:2524001360 DEBUG: OMXClock::OMXSetSpeed(1.00) pause_resume:1

I suppose I should ask if there's anything that can be done to eliminate the continuity errors and see if that fixes the problem?
