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.

we just had another deadlock, looks similar but slightly different than the
previous two. we are getting these every few hours on recent builds, with
1.4.16 it was every couple of weeks on any given machine. It appears from
what I can see that manager logon/logoff at the same time as a phone
changing state and hints updating (sometimes with a reload thrown in) at
least appears to be one trigger. 

russell - if you need access just let me know, we have the core files from
each of these generated as well.
