Summary:                    SIP channel stops processing calls, but no apparent
deadlock
Description: 
Approximately once per week we are seeing asterisk stop processing SIP
calls. The behavior is the same as a deadlock, but core show locks does not
show any evidence that there is a deadlock. 

The only way to resolve is to restart asterisk. 

output of:
core show locks
info thread
thread apply all bt

from the running process is attached.

Im helping dklima with this problem. We update the asterisk to 1.4.15 and
the same problem occurred.

SIP stop work, but we still see the calls going to the queues. The *cli
stop work and no commands were been processed after that(even "core show
locks").

This asterisk has almost 150 SIP extenions, almost 30 queues with 10
members and all of them are configured with member priorities.

This asterisk is working only with SIP, no ZAP and IAX2 at all.

I attached a "gdb thread apply all bt".
