This is the ``I do not care what you are doing, stop right now'' signal. If you send SIGKILL to a process then FreeBSD will stop that process there and then[1]. [1] Not quite true--there are a few things that can not be interrupted. For example, if the process is trying to read from a file that is on another computer on the network, and the other computer has gone away for some reason (been turned off, or the network has a fault), then the process is said to be ``uninterruptible''. Eventually the process will time out, typically after two minutes. As soon as this time out occurs the process will be killed.Received on Sat Jan 15 2005 - 15:30:09 UTC
