Default wait running on TOP

AIX Gurus,
One of my customers complained of wait process running
on TOP. Can anyone help me out on how to trace which process or
program is causing this. I checked exexuting ps aux that shows again
wait consuming memory and the user is root.


Thanks,
Gowrish

If you have many "wait" processes using CPU, you could have bought a smaller
machine.

A "wait" process will run on each CPU when that CPU doesn't have any work to
do.

You customer should be rather pleased to learn that this is the kernel
process that gets scheduled during idle CPU cycles.

The more you see it, the less busy your system is CPU-wise.
