hi
on centos 6, nginx-1.2.2, nginx was compiled with:
--prefix=/usr/local/nginx --user=root --group=root --with-http_ssl_module
--with-ipv6 --with-pcre=/home/nginx/src/pcre-8.20
--with-openssl=/home/nginx/src/openssl-1.0.1c
--with-zlib=/home/nginx/src/zlib-1.2.7
--add-module=/home/nginx/svn/nginx-1.2.2/src/add-on/nginx_subs_filter
--add-module=/home/nginx/svn/nginx-1.2.2/src/add-on/nginx_gunzip
--add-module=/home/nginx/svn/nginx-1.2.2/src/add-on/nginx_lvs_live
--add-module=/home/nginx/svn/nginx-1.2.2/src/add-on/nginx_sniper
some minutes later when launch nginx, i get error(no coredump file, and
workprcess hungs)：
