Summary:                    chan_iax2.c dead lock at chan_iax2.c:2563
Description: 
Hi,

I experienced a dead lock in chan_iax2 today. 

First noticed it when the manager interface stopped responding. I could
hang the cli just by running a "core show channels". The first time the
command didn't complete and from then on no cli commands were accepted. The
lock also happened when I tried to show the current iax channels using
"iax2 show channels".

I attached to the running process with GDB and took a backtrace of all
running threads. 

I also caused a "segfault" with a kill -11 and have also attached the full
backtrace.

I am not 100% certain that the dead lock was in fact in chan_iax2.c, I am
out of my depth and need help with this one.

Thanks & Regards
Jens
