Annoying myth backend problems

Occasionally I run into a problem where I can't delete a show, and the frontend hangs because of it. I restart the backend and frontend, then all systems are go. It looks like when the backend gets in this state that no shows are recorded either.

I just looked through the mythbackend logs to look for anything out of the ordinary. I found one line this morning that looked interesting:

/var/log/mythtv/mythbackend.log.1:2005-12-01 02:58:36.786 unknown socket

There's not too much information there, so I looked for that same error across the archived logs, and found a bunch:

/var/log/mythtv/mythbackend.log:2005-12-01 07:57:30.304 unknown socket
/var/log/mythtv/mythbackend.log.1:2005-11-30 07:40:11.621 unknown socket

/var/log/mythtv/mythbackend.log.2:2005-11-30 02:55:11.343 unknown socket

/var/log/mythtv/mythbackend.log.7:2005-11-24 07:40:56.346 unknown socket
/var/log/mythtv/mythbackend.log.7:2005-11-25 02:40:18.666 unknown socket

What's unusual is that these all happen at two times: 2:40am and 7:40pm. I'm not sure these messages have anything to do with this problem, but it's interesting nonetheless. I don't have any crontabs scheduled, but I'm wondering if this is when the backend is looking for new tv listings.

Something to look into..

Has anyone else out there had the delete problem, or any idea what these messages are?
