Usually the biggest process is the one responsible (note: MFS : > processes do not count, and they are immune from being killed). : :...I suppose it depends on what market you're going for, too. Some :systems (not even necessarily OLD systems, but maybe modern, embedded :ones, too) don't always have the option of having "so much disk space :available". : :Seems like you want your operating system to behave the `correct' way :depending on the environment in which it's being used. : : -- Jason R. Thorpe <thorpej@nas.nasa.gov> If you don't have the disk necessary for a standard overcommit model to work, you definitely do not have the disk necessary for a non-overcommit model to work. If you were to try to implement overcommit protection on a system with insufficient disk space, it probably wouldn't have enough reservable space to run basic system daemons, much less any actual servers. Read the part again where I mentioned the swap requirements for a non-overcommit model to operate at the same level as the current model. -Matt Matthew Dillon <dillon@backplane.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
