But for machines that are really stressed, RH kernel's are quite good in surviving near insane amounts of stress, given the reverse mapping patches coupled with the OOM killer as part of the VM solution. That doesn't mean, however, that the process you intend to keep on going would still be running as every process is somehow fair game with the OOM killer when the machine starts thrashing. OOM killer's goal is just to find the process that consumes the most memory and kill it. So far, the VM solution that Linux has still has a lot left to be desired... -- Paolo Alexis Falcone [EMAIL PROTECTED] To mess up a Linux box, you need to work at it; to mess up your Windows box, you just need to work on it.
