the configuration: use the APC monitor (apc.php) to see how many files are being cached, and how much memory (apc.shm_size) is needed to avoid fragmentation, which will cause the 500 errors. If fragmentation rises quickly to 100%, memory usage is full, and cache full count rises above 0, you will almost surely see “500″ errors. If WordPress is the only PHP script software package on the domain, the following configuration will likely… 7, 1, 2, 0 and 15659.26

APC Cache Considerations for Virtual Hosting Environments
…APC per virtual server. However with 200+ virtual hosts all running PHP script packages, as is the case with a commodity shared hosting server, this will use a lot of memory, and you will need somewhere in the neighborhood of 10-30GB apc.shm_size if you attempt to configure a single APC cache for the entire server. My web hosting server is for a small number of personal clients, so I adjust the APC settings for each individual account, depending… 1, 0, 1, 0 and 3227.49

Apache config for Worker MPM vs Prefork MPM
Some installations of Apache will have been compiled to work with either Prefork or Worker MPM, but most by default are compiled only to work with Prefork. Changing to Worker MPM may allow your server to handle much higher traffic, more user sessions, with less RAM use. Your site or server will not scale well if it is running Prefork MPM. Worker is a bit more difficult to set up properly, and has some restrictions regarding functionality of PHP… 2, 0, 1, 0 and 585.72
WordPress Fail2Ban RegEx for RedHat, CentOS, Amazon Linux

^%(__prefix_line)sAuthentication failure for .* from <HOST>$ |
Apache nohome regex (error_log):
