Correctly Set Apache's MaxClients Directive

By default, the MaxClients parameter has a compiled in hard limit of 256. 2Bits provides a calculation to find the number you need: (Total Memory - Operating System Memory - MySQL memory) / Size Per Apache process.

To keep things working smoothly, you probably want to check your apache error log regularly to make sure MaxClients is not reached.
