Zombie process are the ones for which its parent process
has lost track of.
You can view the zombie processes by using
ps -auwx | grep Z
And to kill them use
kill -9 pid
But normally this wont work. So we will first have to kill
its parent process. And to do this you can use
ps -l pid
to list the pid of the parent process(indicated by PPID)
and then use (kill -9 pid) to terminate it.
If in any case the parent process is the init(1) process
itself, then there is no other option than to reboot the
system.
