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.

I think I've run into the same issue. The system started as:
  AsteriskNOW 1.7.0 distribution
  Asterisk 1.6.2.12
  Dialogic Diva V-4BRI card (with chan_capi and melware divas driver)
with 12 Snom320 and 3 Snom370 phones (all running firmware 7.3.30 and
BLFs).
Every day or so the Asterisk SIP module got freezed and a full Asterisk
restart was necessary to recover it. The call volume is quite lower than
the other reported case.

I can exclude the Dialogic board being part of the issue, as we
temporarily removed it replacing with an external SIP-ISDN gateway, with no
improvements.

I could get rid of this issue after two changes: first, I downgraded
Asterisk to 1.6.2.9; second, I reprogrammed Snom BLFs in order to avoid
phones to subscribe themselves (originally, every phone did show its own
state among the other BLFs). Unfortunately I could not apply these changes
independently, as this is a production system and I had limited time to
work on it, customer was too angry to ask him for some experimenting time
:-(
