Summary:                    Possible deadlock on 1.6.2.12, 14 and 15
Description: 
After hours to days the system appears to reach a deadlocked state.  SIP
phones lose registration, in-flight calls continue, no new calls can be
established.  Need a "service asterisk restart" to get going again.

Problem is usually first observed when phones lose registration (120
seconds between registrations).

System has never been observed to reach this state overnight or on a
weekend so it appears to only happen when the system is actively handling
calls.

Thanks fsegatoz - that's a very interesting read.

We are running 7.3.14 SNOM firmware which is pretty old.

Next time I'm testing with an Asterisk release that exhibits the problem
I'll look for the things pointed out in that article.

We got to 750 calls over 48 hours without a failure running 1.6.2.8 - if
we make it to the end of the week without a lockup I think we'll have
established a known-good configuration we can measure our progress against.
 If I can give the users a good run without failures I should be in a much
better position to bargain with them for test windows where they and I know
the system might fail.
