I am seeing it also just added a bugzilla ticket on it. with a
backtrace. Ticket # 238. Hopefully someone will be able to figuire out
why.

For a couple of months now, I have had an intermitted problem where
the master backend will hang due to slave backend problems. For
example, if you make install on the slave without stopping it, the
master will hang.
I have not been able to pin the problem down very well, but yesterday
it got very frustrating. I had the master recording the Oscars in HDTV.
As far as I know the slave was running happy, I had been using it earlier
in the day, and it dhows no signs of trouble in its logs.
However, as the Oscars are recording, at 7pm (1.5 hours in) the master
wants to tell the slave to record 60 minutes.
Here's abridged sections of the log

Mutex destroy failure: Device or resource busy
And then the master stops, the recording is terminated after 1.5 hours,
and the slave didn't record 60 minutes either (a stub was left in the
database though.)
The only line in the slave's log is:
2005-02-27 18:59:32.821 Changing from None to RecordingOnly
Anybody had this problem? It was very embarassing as I had invited people
back from dinner to see the Oscars in accelerated HD. We got back at
8, so a core hour was lost.
