Hi!
I've been suffering intermitting backend deadlocks since last summer. I
finally took gdb backtrace of the problem and it seems that it same as
ticket #9261. Ticket is low priority so I decided to try to find out
what's going on myself. My C++ is little rusty but I probably figured out
sequence of events but I can't see what other thread could lock
EITScanner::lock. Waiting for that lock causes two other threads to lock.
So what I'm asking what can I do with gdb when it this happens next time?
Is there way to see from gdb what holds that lock? Any pointers are
greatly appreciated. Forgot to mention I'm using 0.24-fixes branch.
Thanks,
Juhani
