NGINX does not start up -> Too Many Open Files

[ehrenwert]

Hello,

at the moment NGINX is not willing to start:

The error:

Jan 09 17:39:01 lichtenberg.ehrenwert-webhosting.de nginx[5200]: nginx: [emerg] open() "/var/www/vhosts/system/example.com/logs/proxy_access_log" failed (24: Too many open files)

I tried to follow https://kb.odin.com/de/115139 to solve this but the error still appears:

ulimit -n
1000000

in NGINX.conf:

worker_rlimit_nofile 65536;

System is Debian 8 on Systemd.

I also mention a lot of errors in php5-fpm.log:

@ehrenwert,

I am pretty sure that you should remove the worker_rlimit_nofile directive.

In fact, this directive is overriding your limits configuration, for which the settings should be correct, in the sense that the value is high enough.

The Nginx override is resulting in a lower limit of open files (i.e. lower than the limit configuration allows).

Removing the Nginx override should do the trick, so it is worth the attempt.

Please change the Nginx settings and reload the Nginx reconfiguration.

Can you report back? I am rather curious whether the above solution helps.

Regards.....
