> The issue  afflict a system that is a x86_64 machine used as callcenter.
> Each Agent is assigned to many queues.
> Occasionally appears this issue:
> Asterisk doesn't read the correct state of the agents. It seems like asterisk queue some process and execute them with some delay
> The agents/users seem to be still connected, only they do not receive calls anymore.
> The state of SIP device stuck to "inuse" causing asterisk not to send anymore call to the agent using this SIP Phone.
> Some agents cannot change they state from ready to pause.
> Or if they are in conversation they are put in pause because a pause input they released minutes before.
> We think that asterisk deadlocks.
> We attach reports of
> gdb -ex "thread apply all bt" --batch /usr/sbin/asterisk `pidof asterisk` > /tmp/backtrace-threads.txt
> asterisk -rx "core show locks" > /tmp/core-show-locks.txt
> asterisk -rx "core show threads" > /tmp/core-show-threads.txt
