This sounds like a scheduled task running.  I am not sure what the
system monitor reports (have not used it).  Does it report a task
running?  One way to check is, from a shell window, type 'top'.  This
command shows a list of active tasks and what percentage of cpu and
memory they consume (this is a standard unix command, also available
in OS/X).  Some system housekeeping tasks do use a fair amount of cpu
for a short while.

Once we know which task is running and using the cpu heavily we can
say more about it.  One old but useful description of unix scheduled
tasks is: 
<http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/custom-guide/ch-autotasks.html>

I hope this is more helpful.
