Random 403 Errors on Ubuntu 10.04

[sgmurphy19]

I have a Ubuntu 10.04 install with ISPConfig3.
I can browse a given url for awhile but eventually it will throw a 403 forbidden error. If I wait about 1 minute then refresh the page will load properly. If I restart apache, the page will reload immediately.

Has anyone else experienced this sort of behavior before?

I am open to any ideas.

Thanks!

Ok, I think I have it figured out. I had the module mod-evasive enable. Disabling this seems to have fixed it. At least I've gone over 100 clicks without generating a 403 error.
