[Asterisk-Users] Crash - What is happening here???

[Michiel Betel]

Matteo,

I AM running -vvvvgc and ulimit -c unlimited (from safe_asterisk) on RH7.2
Thats the weird thing... it crashed without any message..... And looking 
through the
source I still don't see how the Dial could start on a Zombie channel...

But you are right, I'll try to reproduce it tomorrow morning
(Its a production system)
