If that's your only concern, then you shouldn't do anything
about it. Use grep to filter them from your ps output.
To get rid of the "zombie processes", find their parent
processes (with ps) and kill them. (Technical details: The
init process [PID 1] collects all orphaned processes and cares
for them. So if a parent process is killed, its children are
picked up by the init process. If there are any zombies, init
will grab their exit status, and the zombies can finally rest
in peace.)
The real solution is -- of course -- to fix the broken
programs. "Zombie processes" that are hanging around are
always a sign of bad programming.

Oliver
