[mythtv-users] Hang ups after Changing from RecordingOnly to None

I'm having a problem with my MythTV setup.
The backend is hanging rather frequently (1 or more times per day).
In the /var/log/mythtv/mythbackend.log, one of the times it hangs is
after "Changing from RecordingOnly to None". At that point, the frontend
says No recordings scheduled, the backend disappeared, etc. Restarting
the backend ( /etc/init.d/mythtv-backend restart ) will get everything
going again. I also have to Ctrl-Alt-Backspace the X server to get the
frontend talking to the backend again.

Another time it seems to happen is when there is a
"Reschedule requested for id 0" (or -1).

The MySQL database runs on a Dell 1650.

Hopefully some of this info will be relevant, if not, I can email 
anything needed.

Thanks in advance!

Help everyone. If you can't do that, then at least be nice.
