Summary:                    Asterisk locks and no new calls allowed.  Doesn't
crash but have to restart Asterisk to get calls to flow again.
Description: 
Asterisk seems to lock randomly and have not yet found a pattern to why.
Current calls continue without issue but no new calls in or out are
allowed.
Restart the Asterisk application and it will work again for a few hours.

Asterisk was rebuilt with 1.4.9 with DEBUG_THREADS and DONT_OPTIMIZE
enabled then started with /usr/sbin/asterisk -vvvg -c

The backtrace.txt that is attached was gathered in this manor:
ps -aux to get pid of asterisk
[root at pbx] # script /tmp/backtrace.txt
[root at pbx] # gdb /usr/sbin/asterisk pid 
Once you get into gdb, then issue: "set pagination off" to turn of paging.

then issue: info thread
then issue: thread apply all bt
Once you have the output in a file quit out.
Restart Asterisk

I just committed some changes to the DEBUG_THREADS code in 1.4 that should
make debugging these types of problems a lot easier.  Please update to the
latest version of the 1.4 branch, still with DEBUG_THREADS and
DONT_OPTIMIZE set, and include the output of the "core show locks" CLI
command after Asterisk locks up.
