deadlock in Asterisk 1.8.9.0.
<br>
<br>
The system is a x86_64 machine that is being used as a callcenter.
The agents log in via the AgentLogin application, and each
Agent/XXXX channel is assigned to one or more queues. A custom
separate process generates calls into the queues for the agents to
answer. The calls all go out through a SIP trunk, and all of the
agent extensions are SIP. After an hour or so, asterisk deadlocks.
Any attempt to run "agent show" or "agent show online" through the
console hangs. Also, AMI events seem to stop. However, the users
seem to be still connected, only they do not receive calls anymore
(the custom process waits forever for the Originate response). The
deadlock is apparently spontaneous - there is no explicit action
taken by the administrator that seems to induce the issue. I will
try to make sense of the attached traces, but I hope someone on
the list could provide a clue on what to look for.
