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

Applied the patch to SVN Branch for a version of Asterisk
SVN-branch-1.4-r81228M.

This is on a test box and only have SIP and IAX channels available for it,
no ZAP.

Took all the steps that was causing it to crash before with transfers to
the parking lot and it did not lock this time.  I could not say 100% that
it fixed the problem because I was not able to test calls coming in on a
ZAP channel.  I will try to get it put on the production server that does
have ZAP channels to see if the issue is resolved there also.
