No, a kill -9 shouldn't leave memory allocated. However, it is best to try other signals first because it gives the app a chance to clean up before closing (if they handle the signals.) But that's also why they don't necessarily work. SIGHUP (kill -1) is the first thing I generally try. Depending on the app I may try SIGQUIT (kill -15) but generally it's straight to kill -9 if the kill -1 doesn't work. Todd
