Answer / kapil agrawal

I don't believe you can kill zombie process with `kill -9
<pid>`. Zombie process are considered dead. And, you will
have to kill the parent process of the zombie process to
kill the zombie.
use ps -ef| grep "Z" command and ppid of Z process

Answer / venkat

Zombie :
This is the dead process. We can not kill this directly this
process. Since zombie is the child process created by some
parent process.
so sometimes parent process will leave it for future
process. So need to send SIGCHILD signal to parent process
to kill zombie.

command:

" kill -s SIGCHLD <ppid> " ; ppid --> parent process id.

From this way we can kill zombie processes.

Answer / ritesh paul

we can use pstree -paul to find the parent process id
and then kill it by killall and the process id of the parent process.

we can also grep pstree -paul with the child zombie process , it will directly show us the parent process
