[Plesk 11.0.9] Nginx Problem

[vincenzo.t]

Hello,

from about 2 days I have problem with nginx, after httpdm reconfigure I receive this error:

nginx: [emerg] socket() 84.19.XXX.XXX:443 failed (24: Too many open files)
nginx: configuration file /etc/nginx/nginx.conf test failed

I have try to increase the openfile as this guide: http://www.cyberciti.biz/faq/linux-unix-nginx-too-many-open-files/

But not works, at the moment on the server there is 415 2nd level domains, the problem happens after about 390 domains hosted.

Can help me to fix this issue please?

Thanks u.

The first change needs to be done in the startup script of Nginx (/etc/init.d/nginx for example). Add the following line at the top, exactly after the shell script interpreter location (shebang):

ulimit -n 65535

Then open the nginx configuration file (default: /etc/nginx/nginx.conf) and the following line right after the worker_processes entry line worker_rlimit_nofile 20480;

Once both changes are made, run the Nginx lint to make sure no errors have been introduced:

nginx -t

2010/11/01 17:07:46 [info] 9520#0: the configuration file /etc/nginx/nginx.conf syntax is ok
2010/11/01 17:07:46 [info] 9520#0: the configuration file /etc/nginx/nginx.conf was tested successfully

and then restart Nginx if above check is OK

/etc/init.d/nginx restart

Hello

I have already try this solution, but not works.

That error indicates that the amount of files opened at the same time is off limit. By saying you applied the same solution do you mean using the exact numbers? Otherwise if those numbers are lower in your case, just increase them it should resolve that problem with the right number. More howtos on the URls below:
