[cobalt-users] CPU is overloaded - Help

I have had seroius problems with my RAQ2.  The CPU gets overloaded five or
six times a day.  Running 'top' shows the CPU is maxed out, I have seen
numbers as high as 232%.  So obviously some processes are clobering my RAQ2
but I do not know how to identify which process and when.  Is there a log
that monitors CGI?  Or should I be looking at sendmail?

I know this is probably a sign to upgrade but I want to make an informed
decision.  Are the RAQ3i machines considerably faster?  Should I turn my
dual pentium 500 into a CGI server?  Any advice is greatly appreciated.
