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.

denisgalvao: It's tough to say if we are seeing something similar (though
the symptoms are). I have seen instances where show channels doesn't show
the call count at the end and just returns to the cli prompt. That said,
I've seen where it does but SIP processing has also stopped. 

At least several of mine have shown to have occurred during the subscribe
requests, but that doesn't seem to be exclusively related. Do you have
either the output of core show locks or a backtrace from the running
process?

Also - are you running with DEBUG_THREADS enabled?
