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
   dmcpu 177948 1 1 Dec 31 - 0:00 []
   dmcpu 178332 1 1 Dec 31 - 0:00 []

   dmcpu 182928 1 0 Dec 31 - 0:00 []

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?
