Ah, I tried fuser but did not think of using lsof... damnit.
I can't tell what it's doing other than it stops writing to the log
and puts a lock on my RAID array such that I can't stop it. I have not
noticed it happen during playback, so far it has only occured when no
frontend is streaming anything (they may be on, but just at a menu),
and at least the last few times mythcommflag had two processes running
(which is what I have it capped to).
I'll try lsof next time it happens. If it is a file operation on the
RAID array, is there a way to see why it cannot complete the IO
