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.

The problem is that Asterisk completely inutilize the server before
generate any core dumps... this is why i didn't attach any bt or full bt
here.

If I can collect ANY information to help the development team to solve
this issues with the latest version of Asterisk, please tell me how...

I have collected information with several other people having the same
troubles in a variety of hardware and software configurations.

Could this be related to the new libc6 ?

I did use Debian Lenny (testing), but I heard from people using etch
(stable), having the same problems.... random lockups, full CPU ( all cores
) utilization, machine hangs, etc...

Nobody gets any core dumps.
