The load just > 'spikes' sometimes (to 40.00 or so), but immediately starts to go down. Could be Apache restarting a bunch of children all at once. Could be a burst of CGI requests. Try looking at your 'top' snapshots just before and after the spike. Look to see if there are any processes whose PIDs seem to have changed. That might indicate that some processes are getting restarted. Also, look in your apache and mail server log files to see if you're getting a burst of some sort of errors around that time.
