[asterisk-users] Help need for debuging the core file.

Fri Oct 10 15:42:34 CDT 2008

I am running asterisk 1.2.27 and it dead today. The following is the backtrace of core file. Can anybody help me to identify what is the possible cause of crash?
It seems the mysql connection causing problem in Thread 2. But I can not tell what exactly happened.
This asterisk is using as ACD for over hundred agents.
