jpeeler: Also I don't know if I should use patch from
https://issues.asterisk.org/view.php?id=17407
This deadlock only occurred once and I have no idea how to reproduce.  I'd
rather wait for https://issues.asterisk.org/view.php?id=17407 to be reviewed or
committed since they are debating
the merits of that patch on that report.  I'm not sure what davidw is
trying to say over there but I'll put in my 2 cents though.  When it comes
to telephony it is always best not to drop calls or stop the engine.  In my
case the system could not process any calls while the PRI was locked.  And
it stayed locked until I restarted Asterisk.
