If a process corrupts data of any significance after being stopped it should be considered a bug. Obviously if the process has sockets open there is a good chance that timeouts/etc will happen, and the process needs to handle that. However, the same is true if the network goes down/etc, or the system is suspended, or even if the system just gets really highly loaded and doesn't give the process much time. As others have pointed out, once the process stops running it is going to be a relatively high priority for swapping without having to try to do anything else to force things, and it won't come back unless you wake it up. -- Rich
