[mythtv-users] Backend stops responding

I've got an issue where they backend appears to partially stops
responding.  I first noticed this when using mythweb and my list of
recorded programs and upcoming recodings are blank.  The program guide
matrix view works fine as does the list of upcoming recordings.

If I start a frontend on the same machine  I get the same situation.
I saw this previously a few days ago.  Restarting the backend resolves
the problem.

I'm running SVN 10355.

It is still in this "mode" at the moment, below is the output from the
backend and frontend.

Any clues on how to diagnose this one?

Thanks

Stephen.

To clarify the prgram guide did appear at this point although I did
get a pop up saying the connection the backend had gone away.
