How to disable nginx logging, without crit errors?
error_log off - doesnt works, just creates filename \"off\", really, not joke.
error_log dev/null doesnt suppo
Set the logging to stderr (the redirect to /dev/null does not work reliably since from version 0.7.53 /var/log/nginx/error.log) is hardcoded to be used until the config file has been read (http://wiki.nginx.org/CoreModule#error_log).
error_log stderr crit;
Using /dev/null on systems where /var/log/nginx/* doesn't exist will cause nginx to quit.
