frontend cannot connect after trying to play a missing recording

[Mike Rice <mikerice1969@…>]

My wife seems to have found a way to hang the backend. I wasn't there but looking at the logs it appears she tried to play a recording where the file was missing.

Am using:

MythTV Version   : v0.24-109-g945c673-dirty
MythTV Branch    : fixes/0.24
Network Protocol : 63
Library API      : 0.24.20101129-1

From the frontend log:

2011-01-16 16:09:55.200 PlaybackBoxHelper Error: CHECK_AVAILABILITY 'myth://192.168.1.26:6543/5738_20091122115900.mpg' file not found

After a bit it gives up but it cannot re-connect to the backend:

I will attach the frontend and backend logs along with the stack trace for the backend when it was in this state.

If this only happens when trying to play a missing recording it is probably not a big deal since that is probably an anomaly. But I don't know if that's the case.
