"Memory overcommit is a Linux kernel feature that lets applications allocate more memory than is actually available. The idea behind this feature is that some applications allocate large amounts of memory "just in case", but never actually use it. Thus, memory overcommit allows you to run more applications than actually fit in your memory, provided the applications don't actually use the memory they've allocated. If they do, then the kernel terminates the application." Mikkel -- Do not meddle in the affairs of dragons, for thou art crunchy and taste good with Ketchup!
