Check the logs config in /usr/local/apache/conf.d/vhosts/domain.tld.conf
Thank you!
But if you have Nginx+Apache then you need to disable logs in the Apache config files:
/usr/local/apache/conf.d/vhosts/domain.tld.conf
/usr/local/apache/conf.d/vhosts/domain.tld.ssl.conf (if you have SSL enabled)
and in the Nginx config files:
/etc/nginx/conf.d/vhosts/domain.tld.conf
/etc/nginx/conf.d/vhosts/domain.tld.ssl.conf (if you have SSL enabled)
Then restart Apache and Nginx
I don't use Varnish but I guess is the same as Nginx.
You should disable logs in the config files:
/etc/varnish/conf.d/vhosts/domain.tld.conf
/etc/varnish/conf.d/vhosts/domain.tld.ssl.conf
Then restart Varnish
