Thanks for the suggestion.
I was sitting at my desk with another spike occurred and there were no unusual or phantom processes popping up.
MySQL remained at the top of the CPU utilization with, followed by apache2, so I'm starting to believe something is going on with MySQL which is causing the spikes.
Since most of the MySQL tables get mostly reads compared to writes, MyISAM is faster for these "mostly reads", according to what I have read, so I have not changed any off the busy tables to INNODB.
Maybe that is the issue?
But I am hesitant to experiment with changing MYISAM tables to INNODB unless there is clear evidence that altering these tables from MYISAM to INNODB will not create more problems (slowing the DB down), than the 5 or 6 one minute spikes per day.

I am using 48 CPU sunOS server at my work.
