Hi Keith,
I would suggest you investigate what your users aee doing to create zombies,
badly written programs or just bad working
practices.
Either way the only way to remove them is via a reboot- unless someone can
prove me wrong !!

Looking into a user complaint on an AIX 4.3.3, I saw about 170 processes
that looked like this from a ps -ef command:
12:03AM up 18 days, 56 mins, 5 users, load average: 3.24, 3.39, 3.67

The processes could not be removed with a kill -9.
It took a reboot to remove them.
Now, today, on another 4.3.3 box, when I run top I see the following only
until the first refresh of the processes from top:
0 root 0 -20 20k 24k non 3:59 33.2/ 0.1
0 root 0 -20 20k 24k non 3:59 33.2/ 0.1
0 root 0 -20 20k 24k non 3:59 33.2/ 0.1
After top refreshes that first time, I never see them again.
Has anyone seen either of these before? Any theories?
