The service “httpd” appears to be down. CHECK APACH

The problem isn't necessarily with one site on the server, or with any certain user accessing the site too many times, but a total of the number of connections available to Apache.

One of my favorite ways to monitor Apache usage is with the "apachectl status" or "apachectl fullstatus" command, depending on how much information you'd like to receive about the current connections. Once you take a look at that data we have an article about using that information to determine more about the Apache resources here:

Understanding the Apache scoreboard

We also have an article about doing some additional troubleshooting with the Max Request Workers area here:

How do I troubleshoot Apache Max Request Workers errors?

so between those two pages that should give you a good start and tracking down the usage. It's best to try and do this as soon as possible as you notice the problem on the machine for the best results.

cPanel DDOS attack - Mitigate Slowloris Attacks - mod_qos

Apache mod_evasive Mod_evasive is a module available for the Apache HTTP server that can automatically block attacks by rate-limiting any IP that sends too many requests in a short time. Start by installing the module from WHM’s EasyApache 4 interface. Select the Currently Installed Packages profile, search for mod_evasive in the Apache Modules section, and then install it. The default settings are good for most servers, but you can tweak them further by editing the configuration file /etc/apache2/conf.d/300-mod_evasive.conf . You can also whitelist specific IP addresses or classes, so legitimate requests are not blocked. Configure CSF to block attacks While mod_evasive works very well, it only protects the Apache webserver. In order to harden other services as well, you can install the free ConfigServer Security & Firewall (CSF), which also includes a WHM plugin. As the root user, install CSF ...
