CPU maxed out

To whom it may concern:
How do I resolve this message that comes to my email:

“IMPORTANT: Do not ignore this email.
This is cPanel cpuwatch on server.asiasf.com!
While processing, the cpu has been
maxed out for more than a 6 hour period. The current load/uptime line on
the server at the time of this email is
00:03:04 up 35 days, 4:59, 0 users, load average: 1.36, 1.38, 1.36
You should check the server to see why the load is so high and take steps
to lower the load. If you want stats to continue to run even with a high
load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger
then 0 (run /usr/local/cpanel/startup afterwards to pickup the changes).”
