I remember this under 4.3.3. There was a bug that was fixed some time
around ML 3 I think. What ML are you at ?

Hi *,
I have a AIX 4.3.3 server with 2 CPUs. One of the CPUs is always in wio
state. I'm sure that no large I/O operations is done especially between
20 and 23. I'm not familiar with AIX so I want your help to find the
reason of my problem.
Thanks to all
