AIX 5.1 - system load at 70!! and I dont know why

I can't identify any run away procs, like normal when we get high.  Normally 10 is high, 20 is very high, 30 is crazy high.  We are at 70 now!!

The only strange thing I have seen is four mchinfo processes taking up about 5% each.  

any ideas?

Thanks!  Things are back to normal at the moment and no mchinfo procs running.  I will try what you said, if it comes back.

FYI -- no wait really -- all the time was in Kernal and User, with Wait and Idle being basically empty.

I did notice paging faults seemed high.  Bouncing around 300K - 1500K
Normally I see things like 15-900 there. (i.e. withOUT the K)
