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.

Hi ,
I am using 48 CPU sunOS server at my work.

mysql_setpermission
MYSQL_SETPERMISSI(1) MySQL Database System MYSQL_SETPERMISSI(1)
NAME
mysql_setpermission - interactively set permissions in grant tables
SYNOPSIS
mysql_setpermission [options]
DESCRIPTION
mysql_setpermission is a Perl script that was originally written and contributed by Luuk de Boer. It interactively sets permissions in the
MySQL grant tables. mysql_setpermission is written in Perl and requires that the DBI and DBD::mysql Perl modules be installed (see
Section 2.15, "Perl Installation Notes").
Invoke mysql_setpermission like this:
shell> mysql_setpermission [options]
options should be either --help to display the help message, or options that indicate how to connect to the MySQL server. The account used
when you connect determines which permissions you have when attempting to modify existing permissions in the grant tables.
mysql_setpermissions also reads options from the [client] and [perl] groups in the .my.cnf file in your home directory, if the file exists.
mysql_setpermission supports the following options:
o --help
Display a help message and exit.
o --host=host_name
Connect to the MySQL server on the given host.
o --password=password
The password to use when connecting to the server. Note that the password value is not optional for this option, unlike for other MySQL
programs.
Specifying a password on the command line should be considered insecure. See Section 5.3.2.2, "End-User Guidelines for Password
Security". You can use an option file to avoid giving the password on the command line.
o --port=port_num
The TCP/IP port number to use for the connection.
o --socket=path
For connections to localhost, the Unix socket file to use.
o --user=user_name
The MySQL user name to use when connecting to the server.
