Summary:                    ConfBridge crashes Asterisk
Description: 
I have an asterisk installation used mainly for ConfBridge use.

Operating system:

Linux atlas 2.6.18-194.3.1.el5.centos.plusPAE
https://issues.asterisk.org/view.php?id=1 SMP Wed May 19 10:00:02
EDT 2010 i686 i686 i386 GNU/Linux

Usage:

ConfBridge is hosting a small number of conferences with variable number
of atendees.
Typically its 1-2 speaker pr conf room and n number of muted listeners.
Conferences are typically 1-2 hours long.

Description of behaviour:

It seems that the crash occours typically when alot of callers is hanging
up, or something like this. Since the crash typically is after 1-2 hour
(near end or at end of conference). Looks like its happening while users
are leaving conference. But not sure! Ending in total crash of asterisk.


Confbridge configuration:

ConfBridge is used with "cM(something)" for speakers or "mM(something)1"
for listeners.

Codecs / Media:

All codecs are same. aLaw between single endpoint Sonus NBS/GSX gateway.

System hardware:

Dell 2850 4 cpu Intel Xeon with 8GB ram.

---------------------------------------------------------------------- 
I get same error every day now. It does not seem to segfault every time.
Last times now it just hangs. I can connect to cli, show channels, etc. But
no response on SIP.

I just read some other issues. Can my be related to 0017747 ?

I also use asterisk manager http to read channel statistics to monitoring
software.

Attached is todays backtrace from hanging asterisk.

Thanks.
