If the zombies are there due to a signal delivery problem, sending a SIGCHLD to the parent will (probably) solve the problem. But the common case is that the parent is screwed up or simply so badly programmed that the only way of getting rid of the zombies is to kill the parent... Anyway I suppose that sending the SIGCHLD won't do any harm so it may be worth trying. Raúl Núñez de Arenas Coronado -- Linux Registered User 88736 http://www.dervishd.net & http://www.pleyades.net/
