Also
noticed a fairly high load average, it appears you have a lot of processes trying to get on the cpu, for a very long time, over the last 15 minutes you have had 15 load average which is high.

  Hi there,
 

  I have a Sun e4500, running Solaris 2.7   and Oracle 8.1.7.1.0. Everything looks normal from a database   perspective, but when I run "top" it show the kernel being very   hog-like:
 

  load averages: 14.38, 15.18,

  15.18

  Any ideas on what I, as a lowly DBA,
  would be able to check? It's a bit out of my area and I'm   stumped...
 
 

  Thanks!
