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.

callguy: I have the same problems that you mentioned here. I think I can
describe what I have to let you tell me if we are facing the same problem
in the same environment.

Im playing now with r89105, and it worked for about 3 days, 10 min ago I
got the lock, the "*cli> show channels" give me the channels but didn't
give me the active calls count at the end.

All SIP accounts stop to receive calls.

I have almost 20 queues and 150 SIP clients playing with Xlite.

Most time the system run with 30 active calls...

We use only SIP members on the queues, no logged agents here.

I have a similar customer(1.4.13), without problems. The difference
between them couls be the xlite and its SIP subscribe requests... I asked
my customer to disable it, but he didn't had enough time to do that.

Could this problems be related to the amount of SUBSCRIBE requests to SIP?
