Frequently Getting the Error Message "too many requests"

[leland]

Within the last 2 months the error message "too many requests" has started showing up for those using my site.

The site is hosted on a server with a 32 core CPU and 64 GB of RAM. The site usually only uses 10% of the CPU and 15% of the RAM.

I do not have Mod_Evasive installed on the server. In the my.cnf file I have max_connections set to 3000.

I recently changed the PHP-FPM Max Requests from 20 to 200 and this only seemed to make the error message appear more.

I do have all traffic going through CloudFlare, so as far as the server is concerned, all of the traffic is coming from CloudFlare IP addresses. I also use CloudFlare to cache front-end content to reduce the strain on the server.

Is there anything in cPanel/WHM that produces the error message "too many requests" besides Mod_Evasive?

Any help on this would be greatly appreciated.

cPanel/WHM Version:110.0.10
OS: CentOS v7.9.2009

Hey there! Whenever you see that message, it would be best to check the Apache logs at /etc/apache2/logs/error_log to get a more specific error. You could also check the Apache scoreboard with the "apachectl status" command to see the current status of Apache as that would show you if you are experiencing a DoS attack.
