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 just had similar issue with one of my servers running
SVN-branch-1.4-r85720M

Symptoms were:
1. "analog" phones connected over SIP ATAs were not producing any
dialtone.
2. there were no output on the console
3. Even after I executed "sip set debug" no messages started appearing on
the console although tcpdump was showing that SIP packets arrive to the
host.

'restart gracefuly' restored normal work. (And 'sip set debug' started
showing SIP packets on the console)

I havn't collected any evidence (like console output, tcpdump, whatever)
because I was in hury to fix everything - it was prodaction machine.
Because of this I realize this particular report does not worth much. I
just wanted to confim that problem really exists. (Although I'm not sure if
I and callguy have exactly the same problem)
