[mythtv] Master Backend Hangs?

[Thomas M. Pluth]

  I've been keeping current on CVS for the last several months, but in the
last few weeks I've noticed a problem.   Whenever one of my slave
backends shuts down, the master backend stops scheduling recordings.  It
will finish whatever recordings are in progress, but no new recordings
will start.  Restarting the master backend fixes this.

  Here's what I did last night to cause this to happen ;

  23:00 Master and Slave1 both up - Starts Recording
  23:24 Slave1 mythbackend restarted then shut down
  23:31 End Recording
  23:31 Start different recording
  23:46 Start up Slave2
  23:55 Shut down Slave2

  I don't see "left the building" messages for the second shutdown of
Slave1 or for the shutdown of Slave2.

  Any ideas?
