Help CPU pegged at 96% but cannot find culprit

[Romeo Theriault]

Fresh install of red hat enterprise AS 4 update 2 with all the  
patches, running as a web server(apache) with coldfusion. The cpu is  
pegged at around 96% with 65 or so under user and 30 or so for the  
system. I've done a top and nothing is showing as using this much  
cpu. I downloaded ibm's performance tool nmon and tried it and it's  
showing the same stats. How can I find the process which is taking up  
so much cpu. Thank you very much.
