Simply because the process is supposed to be run chrooted so it should not have file system access anymore after the fork(). Thus it cannot remove these file system entries. Also, when performing a soft restart, the new process renames those entries in order to bind to the new sockets, so the old process does not know what name the old socket gets. However, I agree that during debugging sessions, it might make sense to get rid of these entries. Maybe we should just attempt to remove them upon exit (when the process has not been replaced). I don't really know. I must confess that this has never bothered me. Willy
