How do I find the CPU hog?

I've got a 9406-510 running at V3R7 with the "latest" cumes.  Over the
past few days, we've been seeing the CPU running consistently in the 75%
- 90+% range all day long.  A cursory look at the jobs in WRKACTJOB
showed a total of about 40% when the display header shows 74%.  Our job
queue is beginning to get backed up a bit.  Disk uitilization is
currently at 81%, BUT we've had this condition for at least a few weeks
now.  This system hasn't seen disk utilization under 70% in a long LONG
time.

Where do I start looking?
