Workaround for "configuration file test failed" under OpenVZ. If nginx was used under OpenVZ and a container with nginx was suspended and resumed, configuration tests started to fail because of EADDRINUSE returned from listen() instead of bind(): # nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: [emerg] listen() to 0.0.0.0:80, backlog 511 failed (98: Address already in use) nginx: configuration file /etc/nginx/nginx.conf test failed With this change EADDRINUSE errors returned by listen() are handled similarly to errors returned by bind(), and configuration tests work fine in the same environment: # nginx -t nginx: the configuration file /etc/nginx/nginx.conf syntax is ok nginx: configuration file /etc/nginx/nginx.conf test is successful More details about OpenVZ suspend/resume bug: https://bugzilla.openvz.org/show_bug.cgi?id=2470
