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.

i've catched another deadlock. source of this was call to the queue which
has ring all strategy with 5 phones (some SIP and some Local channels). I'm
also using BLF on several phones. I've attached 'core show locks' and gs
snapshot of asterisk process 'thread apply all bt full'. See attached file
deadlock-festr-2.
