…sit” 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” […]
…e ForceSSL and auth_type. For a production server, SSL should be ON and auth_type http is better; http auth uses MySQL user/pass combinations to restrict access to user-specific databases.
…millions of malicious and compromised servers and personal computers. Reconfigured Apache web server, PHP and MySQL to better utilize the server’s horsepower. Cpanel’s efault Apache and MySQL configurations were limiting the number of concurrent user sessions the server could handle. Changed PHP to run as FastCGI (fcgid) and recompiled Apache to better handle the needs […]

…, then you should do more research. Recompiling is not a trivial process. I found that my server had much better memory usage under Worker MPM, however: some scripts (squirrelmail, phpmyadmin) do not work on a per-domain basis and must be run direct to the actual server process with symlinked directories. This is much more […]
APC cache does not work well in a virtual hosting environment unless PHP is running as FCGID, and every individual virtual host has a unique PHP.ini and a unique fcgiwrapper. This is not the case with many virtual hosting environments because the memory and CPU requirements are too great. I suggest using Virtualmin for a […]
