What is your mysql version?
Check /var/lib/mysql/<hostname>.err log for any errors.
Is apache still making troubles for you?
I really don't know whats the problem with my server.
Apache is consuming almost all my CPU, but is probably caused by mysql.
The version of mysql is: MySQL 5.0.51a
I checked the error logs, and is nothing estrange there.
I don't know what to do next.
