Summary:                    Random deadlock in res_config_mysql
Description: 
Asterisk randomly stops processing SIP calls. I cannot find a pattern of
external events triggering it. I have around 700 registers in realtime....

Asterisk version 1.4.32

I have compiled asterisk with DEBUG_THREADS. When this happers 'core show
locks' presents this... I am reporting 4 events (core show locks)...

I believe this bug is the same issue
https://issues.asterisk.org/view.php?id=15090 (fixed for 1.6.x but not fixed
for 1.4.x)

---------------------------------------------------------------------- 
Asterisk randomly stops processing SIP calls but will not crash. I can stop
it with a "stop now" in the CLI. What would be the best method to generate
the backtrace?

   1. get PID with ps aux
   2. enter "gdb /usr/sbin/asterisk PID"
   3. enter "bt" while in gdb (or of the "bt full")
   4. enter "thread apply all bt"
