[asterisk-dev] Asterisk core dump problem

[cr rajesh]

Hi,

I'm running Asterisk v 1.2.0 in our Servers. We are
creating conference dynamically using Meetme
application with dq flag. We are currently testing our
application and over a period of time the asterisk
gets crashed with message -Segmentation fault (core
dumped). In average it happens once in a day.

All the times the core dump happens exactly after the
MeetMe in the Dial plan. I've listed below all the
logs and other information. Please help me in solving
this problem. Also, please let me know if you need any
other information.

Thanks,
Rajesh.
