Re: nginx keeps crashing

April 05, 2013 10:13AM
Hello,

Thanks Maxim for looking into my issue.

I recompiled nginx with no 3rd party module & debugging enabled.

[root@localhost sbin]# ./nginx -V
nginx version: nginx/1.2.8
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC)
configure arguments: --with-http_stub_status_module --with-http_perl_module --with-http_flv_module --with-http_mp4_module --with-debug

there is no nginx.core file found in /home/core/ , thats the path specified in nginx.conf

but i still keep seeing
