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.

hi,
hope your systems are doing fine :)
i have a question. i have noticed before my deadlocks there were transfers
with
call came in on queue
-> someone (10) picked up
-> transfered it to somebody (20)
-> somebody (20) was busy or nav
-> someone (10) speaks with incomming caller again
-> someone (10) transfered it to another ex (30)
-> another ex (30) picked up the phone and they were transfered.

do you have logs from the console? can somebody look if there are some 
  == Extension Changed 90[custom] new state Hold for Notify User 70
  == Extension Changed 90[custom] new state Hold for Notify User 71
  == Extension Changed 90[custom] new state Hold for Notify User 72
before your deadlocks?

i have tried to reproduce this, but if i test it in the evening and the
people are not registered there are no hints :(

maybe its not only a hint problem.
and maybe that would explain why it deadlocked twice a day by your issue
and only every 1-2 weeks by my issue.

Thank you!
