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 am still experiencing this problem. Once per day. Average number of daily
calls is 5500. Mostly outbound calls, 16 agents.

With Asterisk 1.4.15, the crash happened 3~4 times per day.

After installing the 92102 trunk update, the Asterisk stopped crashing,
but still, sip channels get lock once a day. So I am forced to restart the
asterisk.

I tried to reduce the rtptimeout and rtpholdtimeout options, but it didn't
helped.
