Nginx, huge size of /usr/share/nginx/on

Question

I have a debian with WordPress on dedicate server using Nginx.

During a du/df check, I catched une very huge file "/usr/share/nginx/on" with about 400Go size Is it ok ?

If not, what is this file and how to reduce size ?

Thank

This is an access log, a result of NGINX misconfiguration. This isn't fine.

In your NGINX configuration, you likely have:

access_log on;

This is incorrect and should be changed to the desired path of an access log. (Or simply remove the directive if you don't care about access logs).
