HP Help! Zombies
Hello, quick question:

I have a zombie process listed with 'top'

Could someone help me find out what it the PID is for it,
so I can kill $PID.
Code:
$ model
9000/800/rp3440

HP-UX bigassserver B.11.31 U 9000/800 3085785128 unlimited-user license
thanks!

Contrary to popular belief you can't always kill a zombie.

Without more detail, this sounds spurious.

One, single zombie isn't something I'd necessarily be alarmed about, though. It's when they accumulate that something's gone wrong.

You can't kill that which is already dead.

Actually, you can kill zombies; they just won't notice that they've been killed (again).
Code:
kill 0 pid_of_zombie

will complete successfully telling you that the zombie hasn't been reaped yet.
Code:
kill TERM pid_of_zombie

will send a SIGTERM signal to the zombie and will complete successfully (assuming you have permission to send a signal to that process), but the zombie will never notice that the signal was sent nor be able to act upon that signal.

Code:
 ps -ef|grep efu   
root 19693  2564  0 13:56:30 ?         0:00 <defunct>
myusernamehere 19724 12092  0 13:56:39 pts/tk    0:00 grep efu


.... yields my user name... that was not helpful.

I'd like to know how to find and kill this zombie process... if you want a ps -ef just ask. I can't find its parent. It's been on 'top' for a month or so now...
note, i will not post my ps -ef, usernames in prod env. sorry.

suggestions? thanks..
