Summary:                    [patch] Deadlock of SIP takes out server
Description: 
This happens with both asterisk 1.8.0 and 1.8.2.3.  The server will take
calls for some amount of time (less than a day - within a few hours) can
all of the sudden will stop responding on the SIP.  I can see with a
netstat -na that many of the receive queues (including 5060) are full of
waiting packets.

I have compiled asterisk with DEBUG_THREADS and DONT_OPTIMIZE and was able
to do both a core show locks and a backtrace for two of the crashes.  

The majority of our calls are SRTP and also the majority use fastAGI if
that helps.

Hi... just checking back in.  If no one is available to work the issue I am
wondering if perhaps some quick analysis could be done on more or less what
causes the deadlock?  

I am guessing it is around blind transfers - perhaps if I had some more
clear idea I could devise a load test that would allow me to do some work
on the issue.  

Thanks!
