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.

Yes I have a similar problem.
Asterisk version 1.4.15
But not compiled with option to show core locks
However we get deadlock several times daily and can reproduce the deadlock
with core show channels command

I have been watching this bug with great interest.
I don't know what I can do to help...

We are also running a busy call center with 2 PRI circuits
About 20 agents and 20 queues

Our server is running stock 1.4.15 with no patches.
