Description:Hello,

First time I file a bug, please let me know what I am doing wrong.

We have 6 asterisk servers 1.4.2 used to load balance traffic, around 40 calls per server. Asterisk processes SIP2SIP calls.

Asterisk is running on debian sarge 2.4.27-3-386,asterisk_safe with -g option.

Randomly asterisk crashes, creates a core.dump and is restarted by asterisk_safe. All calls are cut, the logs in /var/log/asterisk/messages show the restart logs.

I have an asterisk core dump and I enabled the flags DEBUG_THREADS, DONT_OPTIMIZE before compiling and provide here a backtrace.

I can provide more info if needed...
thanks

Please upgrade to the latest code in the 1.4 branch, or 1.4.3 when available.  I think this may have already been fixed.

$ svn co http://svn.digium.com/svn/asterisk/branches/1.4 asterisk-1.4

Problem is fixed in 1.4 branch.
Thanks!
