Summary:                    random deadlocks - SIP messages not being processed
Description: 
Just upgraded to Asterisk 1.8.2 for production and we're getting random
deadlocks.  When this happens, it looks like Asterisk is not able to
process new SIP messages.  Any INVITEs or REGISTERs that arrive are not
being outputted to the console or logs.

This seems to happen randomly.  I have not been able to reproduce it at
will although it does happen about 5-10 times per day.  The server is
handling about 2000 calls/day, so it's not really that busy.  There are
about 75 phones connected to the server.

Please see attached backtrace and lock output for more information.  It
shows the deadlocks but I'm not sure which is the root issue here.
