Hi,

Thank you for your quick response.

Here is the output of nginx -V :

nginx version: nginx/1.2.1
TLS SNI support enabled

I added this two lines for core dump in nginx.conf :
worker_rlimit_core 500M;
working_directory /path/to/cores/;

But I think I have to compile nginx with backtrace module to dump backtrace.

What other includes do I need in my nginx.conf ?

Thanks.
