Summary:                    Asterisk becomes unresponsive and seems to be locked
waiting on a mutex
Description: 
After a restart, Asterisk became unresponsive. The Asterisk console still
worked, but no calls could be made. After a period, Asterisk was killed,
and a coredump generated.

The coredump shows that there were 1034 threads, 1015 of which were in
__lll_mutex_lock_wait () (/lib/libpthread.so.0). Below is a full backtrace
for one of these threads. All the waiting threads refer to the same lock
(lock_addr=0x6650f0).

Below is also a listing of the logs for the period during which it was
unresponsive.

Please turn on DEBUG_THREADS in 'make menuselect' and get a 'core show
locks' when the lockup occurs.
