I've likely found a rather repeatable bug.
Master back-end with encoder 1 (PVR-250) and sql server and (nfs
exported) file storage for mythtv
EPIA M6000 slave backend with encoder 2 (PVR-350) and front-end
connected to TV using TV-out of PVR.
Situation: slave backend already running
start master back-end
slave will connect to master well.
reboot slave backend
after reboot slave re-connects
start using myth to browse through recorded programs
and observe master backend crashing with: mutex destroy failure,
resource busy or in use.
Logs from the master backend:
root at repeater:~# Starting up as the master server.

Mutex destroy failure: Device or resource busy
As you can see, its CVS of march 31.
Related bug: the frontend waits forever on the crashed backend and does
not return. At least not within 5 minutes, which is how long my patience
- Has any code gone into CVS to solve something like this?
- Can somebody point me to a description of the protocol used? I'd like
to take a look at it, C++ is not something i easily read... And time i
tend to be short on.
With a current description I might come up with possible improvements.
