Summary:                    [patch] Mutex 'dialog' freed more times than we've
locked !       and      Error releasing mutex.
Description: 
Hi,

Have a system (asterisk) crash several times a day that causes all
communications to halt abruptly and prevents any new call to go through.

Cheers,

Hi bbryant,

The patch has solved the mutex pb. as  the system run for a week witout a
single crash. However after that week, the system did crash with another
mutex :

[Oct 12 08:21:10] ERROR[18293] lock.c: chan_dahdi.c line 2053
(my_unlock_private): mutex '&p->lock' freed more times than we've locked!
[Oct 12 08:21:10] ERROR[18293] lock.c: chan_dahdi.c line 2053
(my_unlock_private): Error releasing mutex: Operation not permitted

This pb is scarce but still annoying. Have attached gdb and log files.

Cheers,
