Hi,
last few years I using nginx on very busy websites and all time all working
fine, never I don`t have problem with nginx crashing but now I move my
websites to new server and I using same settings like on old server but now
nginx crashing every few hours, here is nginx -V info:
nginx version: nginx/1.8.0
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-16) (GCC)
configure arguments: --with-http_stub_status_module
--without-mail_pop3_module --without-mail_imap_module
--without-mail_smtp_module --without-http_autoindex_module
--without-http_browser_module --without-http_geo_module
--without-http_empty_gif_module --without-http_memcached_module
--without-http_ssi_module --with-debug

centos-release-6-7.el6.centos.12.3.x86_64
