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.

SQL::Translator::Producer::MySQL(3pm) User Contributed Perl Documentation SQL::Translator::Producer::MySQL(3pm)
NAME
SQL::Translator::Producer::MySQL - MySQL-specific producer for SQL::Translator
SYNOPSIS
Use via SQL::Translator:
use SQL::Translator;
my $t = SQL::Translator->new( parser => '...', producer => 'MySQL', '...' );
$t->translate;
DESCRIPTION
This module will produce text output of the schema suitable for MySQL. There are still some issues to be worked out with syntax
differences between MySQL versions 3 and 4 ("SET foreign_key_checks," character sets for fields, etc.).
ARGUMENTS
This producer takes a single optional producer_arg "mysql_version", which provides the desired version for the target database. By default
MySQL v3 is assumed, and statements pertaining to any features introduced in later versions (e.g. CREATE VIEW) are not produced.
Valid version specifiers for "mysql_version" are listed here
Table Types
Normally the tables will be created without any explicit table type given and so will use the MySQL default.
Any tables involved in foreign key constraints automatically get a table type of InnoDB, unless this is overridden by setting the
"mysql_table_type" extra attribute explicitly on the table.
Extra attributes.
The producer recognises the following extra attributes on the Schema objects.
field.list
Set the list of allowed values for Enum fields.
field.binary, field.unsigned, field.zerofill
Set the MySQL field options of the same name.
field.renamed_from, table.renamed_from
Use when producing diffs to indicate that the current table/field has been renamed from the old name as given in the attribute value.
table.mysql_table_type
Set the type of the table e.g. 'InnoDB', 'MyISAM'. This will be automatically set for tables involved in foreign key constraints if it
is not already set explicitly. See "Table Types".
Please note that the "ENGINE" option is the preferred method of specifying the MySQL storage engine to use, but this method still works
for backwards compatibility.
table.mysql_charset, table.mysql_collate
Set the tables default charater set and collation order.
field.mysql_charset, field.mysql_collate
Set the fields charater set and collation order.
