Backtrace of system after crash...  running on the latest SVN snapshot..  it doesnt seem to go into a deadlock state..  asterisk compiled with malloc_debug, debug_threads, Better_backtraces, dont_optimize  options set.. it may often core dump 6 or 7 times before getting itself straight..  meaning if it core dumps once it will core dump right away after safe_asterisk starts it..  this was a single core dump..  and then safe_asterisk restarted it as normal..  the end of the .pcap file is where the crash occured..  it is a port 5060 capture of the NIC asterisk is bound to.  plugging the gateway in does not cause a crash instantly..  the crash occurs some hours or a day or so later..  currently there are 2 of these gateways along with a polycom phone and a couple aastra phones running..  the gateways are 192.168.10.202 and 192.168.10.247.
Connected to Asterisk SVN-branch-1.8-r391778 currently running on Maxx-home-ssd (pid = 16460)
Verbosity is at least 10

> Segfault occurs whether system is idle or is in-use. it will crash within a day or two even if 0 calls are made on it.  running under safe_asterisk, results in multiple crashes within a few minutes until eventually system ends up in a MUTEX lock. over 3 gigs of RAM available and plenty of disk space at time of first crash. Possibly related to the 96 port gateway producing 96 SIP registrations all at once?
