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.

I can confirm that re-enabling res_timing_dahdi has stopped the deadlocks
on my PBX.  MOH still seems to hook into res_timing_pthreads for something,
my 'module show like timing' looks like this

pbx*CLI> module show like timing
Module                         Description                             
Use Count 
res_timing_dahdi.so            DAHDI Timing Interface                   1 
       
res_timing_pthread.so          pthread Timing Interface                 2 
       
2 modules loaded

anyway, as I expected, this has killed my MOH.  MOH is not working
correctly with res_timing_dahdi enabled for some reason.
