Summary:                    [patch] app_queue crashes randomly, it seems to be
during call-transfers
Description: 
We have had lot's of crashes in app_queue in our system. As the system was
never really stable it received software upgrades as well as totally new
(IBM) Hardware.

The crashes to app_queue are once or twice a week, sometimes more often,
mostly we have NO indication in the asterisk Log-Files. Ultimately (and
this may be because of a debug recompile) we get lines in the error log
like these:

[Aug  7 19:07:23] ERROR[27115]
/usr/local/src/asterisk-1.4.26/include/asterisk/lock.h: app_queue.c line
2559 (update_queue): Error obtaining mutex: Invalid argument

Funny thing is the system crashed on August the 6th (I do not have a
coredump) and on August the 7th at nearly the same time:

Aug  7 19:07:23 logitravel-voip2 kernel: [7905412.479435] asterisk[27115]:
segfault at d5d69fd0 ip b798757e sp b5258ef0 error 5 in
app_queue.so[b7984000+1c000]
Aug  6 19:00:57 logitravel-voip2 kernel: [7720142.069484] asterisk[7274]:
segfault at bb0f1be8 ip b796e57e sp b55f8ef0 error 4 in
app_queue.so[b796b000+1c000]


I have attached a backtrace, with bt, bt full and threads applied. I hope
it's any help because our client (a medium sized call-center) is waiting
for a solution.

We consider right now downgrading to debian stable (1.4.21.2)
