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.
