Hi,
I have got a solution for removing zombie process on servers(linux servers). We neither
need to restart the server nor run script to do this all we have to do is
just run the following command.
ps -el | grep 'Z' The output of the above command will be something like this F S UID PID PPID C PRI NI ADDR SZ WCHAN TTY TIME CMD 4 Z 0 668 4243 0 78 0 - 0 exit ? 00:09:39 VV 4 Z 0 1403 4243 0 78 0 - 0 exit ? 00:08:11 VV 4 Z 0 1613 4243 0 78 0 - 0 exit ? 00:09:43 VV 4 Z 0 2202 4243 0 78 0 - 0 exit ? 00:09:25 VV 4 Z 0 2382 4243 0 82 0 - 0 exit ? 00:08:07 VV 4 Z 0 2618 4243 0 78 0 - 0 exit ? 00:09:52 VV 4 Z 0 2714 4243 0 77 0 - 0 exit ? 00:09:51 VV 4 Z 0 2741 4243 0 78 0 - 0 exit ? 00:09:18 VV 4 Z 0 2956 4243 0 76 0 - 0 exit ? 00:07:41 VV 4 Z 0 3030 4243 0 75 0 - 0 exit ? 00:00:06 VV 4 Z 0 3125 4243 0 83 0 - 0 exit ? 00:08:09 VV 4 Z 0 3260 4243 0 83 0 - 0 exit ? 00:09:02 VV 4 Z 0 3480 4243 0 77 0 - 0 exit ? 00:09:37 VV 4 Z 0 4151 4243 0 76 0 - 0 exit ? 00:08:49 VV 4 Z 0 4899 4243 0 76 0 - 0 exit ? 00:00:04 VV 4 Z 0 5099 4243 0 81 0 - 0 exit ? 00:09:32 VV 4 Z 0 5667 4243 0 76 0 - 0 exit ? 00:07:58 VV 4 Z 0 5778 4243 0 78 0 - 0 exit ? 00:09:40 VV 4 Z 0 5956 4243 0 82 0 - 0 exit ? 00:10:19 VV 4 Z 0 7035 4243 0 80 0 - 0 exit ? 00:10:04 VV 4 Z 0 7448 4243 0 83 0 - 0 exit ? 00:08:23 VV 4 Z 0 7757 4243 0 83 0 - 0 exit ? 00:10:06 VV 4 Z 0 8219 4243 0 82 0 - 0 exit ? 00:10:11 VV 4 Z 0 8262 4243 0 76 0 - 0 exit ? 00:07:55 VV 4 Z 0 8631 4243 0 76 0 - 0 exit ? 00:05:57 VV 4 Z 0 8728 4243 0 76 0 - 0 exit ? 00:00:04 VV 4 Z 0 8944 4243 0 76 0 - 0 exit ? 00:00:04 VV 4 Z 0 9431 4243 0 80 0 - 0 exit ? 00:09:57 VV 4 Z 0 9577 4243 0 83 0 - 0 exit ? 00:09:00 VV 4 Z 0 9762 4243 0 76 0 - 0 exit ? 00:00:04 VV 4 Z 0 10263 4243 0 76 0 - 0 exit ? 00:07:57 VV 4 Z 0 10960 4243 0 83 0 - 0 exit ? 00:08:13 VV 4 Z 0 11526 4243 0 78 0 - 0 exit ? 00:10:08 VV 4 Z 0 11952 4243 0 78 0 - 0 exit ? 00:08:05 VV 4 Z 0 13339 4243 0 78 0 - 0 exit ? 00:08:12 VV 4 Z 0 14776 4243 0 76 0 - 0 exit ? 00:00:04 VV 4 Z 0 15016 4243 0 83 0 - 0 exit ? 00:08:09 VV 4 Z 0 15163 4243 0 76 0 - 0 exit ? 00:07:44 VV 4 Z 0 16673 4243 0 76 0 - 0 exit ? 00:00:04 VV 4 Z 0 17057 4243 0 79 0 - 0 exit ? 00:09:33 VV 4 Z 0 17095 4243 0 75 0 - 0 exit ? 00:00:04 VV 4 Z 0 17155 4243 0 81 0 - 0 exit ? 00:09:44 VV 4 Z 0 17760 4243 0 81 0 - 0 exit ? 00:09:42 VV 4 Z 0 18088 4243 0 83 0 - 0 exit ? 00:10:00 VV 4 Z 0 18274 4243 0 76 0 - 0 exit ? 00:07:45 VV 4 Z 0 18744 4243 0 83 0 - 0 exit ? 00:09:18 VV 4 Z 0 19227 4243 0 82 0 - 0 exit ? 00:10:10 VV 4 Z 0 19288 4243 0 79 0 - 0 exit ? 00:09:23 VV 4 Z 0 19316 4243 0 78 0 - 0 exit ? 00:09:51 VV 4 Z 0 19654 4243 0 78 0 - 0 exit ? 00:09:32 VV 4 Z 0 19695 4243 0 77 0 - 0 exit ? 00:09:51 VV 4 Z 0 20190 4243 0 78 0 - 0 exit ? 00:08:55 VV 4 Z 0 20602 4243 0 76 0 - 0 exit ? 00:07:56 VV 4 Z 0 21455 4243 0 76 0 - 0 exit ? 00:07:54 VV 4 Z 0 21687 4243 0 83 0 - 0 exit ? 00:09:16 VV 4 Z 0 22785 4243 0 84 0 - 0 exit ? 00:08:08 VV 4 Z 0 22855 4243 0 78 0 - 0 exit ? 00:09:39 VV 4 Z 0 23330 4243 0 78 0 - 0 exit ? 00:09:37 VV 4 Z 0 23405 4243 0 82 0 - 0 exit ? 00:10:24 VV 4 Z 0 23600 4243 0 83 0 - 0 exit ? 00:08:45 VV 4 Z 0 24578 4243 0 76 0 - 0 exit ? 00:07:40 VV 4 Z 0 24846 4243 0 75 0 - 0 exit ? 00:00:04 VV 4 Z 0 25661 4243 0 78 0 - 0 exit ? 00:08:04 VV 4 Z 0 26718 4243 0 76 0 - 0 exit ? 00:07:56 VV 4 Z 0 26908 4243 0 82 0 - 0 exit ? 00:09:45 VV 4 Z 0 27554 4243 0 77 0 - 0 exit ? 00:09:27 VV 4 Z 0 28478 4243 0 82 0 - 0 exit ? 00:08:10 VV 4 Z 0 28553 4243 0 78 0 - 0 exit ? 00:10:21 VV 4 Z 0 29034 4243 0 76 0 - 0 exit ? 00:09:24 VV 4 Z 0 29173 4243 0 82 0 - 0 exit ? 00:09:54 VV 4 Z 0 29193 4243 0 82 0 - 0 exit ? 00:09:04 VV 4 Z 0 29722 4243 0 78 0 - 0 exit ? 00:09:34 VV 4 Z 0 30856 4243 0 78 0 - 0 exit ? 00:09:11 VV 4 Z 0 30999 4243 0 83 0 - 0 exit ? 00:09:04 VV 4 Z 0 31057 4243 0 78 0 - 0 exit ? 00:09:51 VV 4 Z 0 31274 4243 0 76 0 - 0 exit ? 00:07:51 VV 4 Z 0 31735 4243 0 76 0 - 0 exit ? 00:00:04 VV 4 Z 0 31924 4243 0 81 0 - 0 exit ? 00:08:01 VV 4 Z 0 32121 4243 9 78 0 - 0 exit ? 00:10:11 VV
then we have to look into PPID(parent process i’d) and kill that process,
here the PPID is 4243
so the command to be executed will be
kill -9 4243
