Summary:                    Crash in iax2_destroy at chan_iax2.c:1309
Description: 
Brand new system taken from 1.4svn (r129803).

The machine is at my house and the network is particularly bad today
(http://bugs.digium.com/view.php?id=22#60%
packet loss).

I have a caching name server, and have registrations to three Asterisk 1.4
machines I own (trunking enabled).

There are no users on the machine as it is being built for production for
next week.

With no activity except for the outgoing registrations and qualify
statements, Asterisk crashed with the following:

http://bugs.digium.com/view.php?id=5  0xb7e5249e in clone () from
/lib/tls/i686/cmov/libc.so.6

The machine is:

2.6.18-5-686 http://bugs.digium.com/view.php?id=1 SMP Tue Dec 18 21:24:20 UTC
2007 i686 GNU/Linux

It crashed twice earlier (within 10 minutes of each other), but has not
crashed in the last 2 hours.

The only difference I can see (seeing as the box is doing nothing) is that
in the period where it crashed twice, the packet loss was extreme.

This may prove to be a difficult one to track down, however I have
recompiled Asterisk with DEBUG_THREADS and DONT_OPTIMIZE and will upload
another core if I get one.
