Myth backend has crashed twice this week

Two nights this week I have had my masterbackend crash while I have been watching a recorded show.  The master backend was also recording new shows at the same time.  Normally not a problem.  I just enabled comm flagging as soon as the show starts though.  Last night I turned that off.  Hopefully that was what was causing my problems.  I should know in another week or so.  Not a huge deal but still a pain.  Think since  I have been using mythtv the masterbackend has crashed 3 times while recording shows.  Not to bad but still not good to have it crash at all.  Hopefully this change will get me back on track.
