httpd using all processor

[toolz]

Apache 2.2.14
Php 5.2.11

On freebsd 6.4 32bit.

My httpd is currently eating all my proc, load averages are so high:

load averages: 28.95, 26.77, 27.68

This happens for few days, then it stops without no modification. On and on.

Logs show nothing suspicious..

I believe someone is trying to attack or to crash apache on my server and I have no idea how to track him nor stop him.

Any idea on what should I do?
Thanks.

You have to figure out what is causing it. Check server-status

 

[toolz]

Server-status does not work, I tryed almost everything.

I keep getting "500 Internal server error" page

What does /var/log/httpd/error_log say

 

[toolz]

client denied by server configuration: /var/www/html/server-status

though I modified to:

<Location /server-status>
SetHandler server-status
Order Allow,Deny
Allow from all
Deny from .example.com
</Location>
