What does your Linux system do when it completely runs out of memory? When even virtual memory is exausted?
As a last resort, Linux turns your processes over to a dark angel known as the OOM Killer. The OOM Killer has the grisly job of picking which process needs to die in order to get your system back to a manageable state. It actually follows a rather precise formula, endeavoring to make a decision which will be most convenient to the user and fair to the running processes.
