Summary:                    Asterisk 1.4.15 uses 200% of CPU randomly and
crashes the machine.
Description: 
I have several Asterisk servers running all over the country and when I
upgraded those servers, they all started to randomly crash.

The unique thing I have detected is that on Core 2 Duo machines the CPU
Usage goes around 200% CPU on top and on Xeon Quad-Core machines I get
around 360% usage of cpu, causing random crashes and completely inutilising
the machine.

Asterisk runs normally and this is a totaly random effect.

Ok, I'll send you a Valgrind ASAP...

For now, to reproduce the problem, just follow:

* Install Debian Lenny ( some partners reported that the error occurs on
etch too... )
* apt-get update
* apt-get dist-upgrade (from Debian official repositories)
* apt-get the necessary packages for Asterisk compilation...
* Install  the libpri from Debian repository (libpri-dev, libpri1.0) ( as
the current libpri doesn't compile anymore and no official correction has
been released....)
* Compile zaptel latest
* Compile Asterisk 1.4.15 and Asterisk-addons latest
* Run Asterisk with a Zaptel hardware (tested with wcte12xp)
* Keep some calls running on the server with MixMonitor for some hours
(don't know if without MixMonitor the error reproduces as I've tested it
with MixMonitor only...)
* Asterisk will hang soon...
