Apache Out of Control
I could use some help from the expert team. :-) It appears that apache is running my CPU usage up. See below. Any ideas how I can tune apache to run smoothly? Thanks!

ASKER
The pages are written in PHP. The site is an online store. We are also running MySQL and the store accesses the database. Seems to me like the problem is with apache and not MySQL but I'm only basing this off of the fact that apache has spawned numerious processes and the MySQL information I looked at showed minimal database usage.

It looks like you are running MySQL also, by chance are you running some type of application under Apache that is accesing MySQL? Could it be chewing up your CPU?
