Why? The KILL signal cannot be handled by the process being so killed. This means blasting away with kill -9 may leave child processes of a parent orphaned, the filesystem littered with temporary files, shared memory segments active, lingering sockets, and any atexit(3) code unexecuted. The result? A system in taters, and an increased risk of unanticipated and hard to debug problems. |
