Apache/PHP Issues when upgrading to RH Enterprise

I finally upgraded my server from RH7.3 to the RedHat Enterprise - we did a new install before copying over our sites. That's when my trouble started.

[root@www pals]# httpd -v
Server version: Apache/2.0.46
Server built: Nov 12 2003 10:53:55

With some frequency, some of my users (myself included) get a timeout when submitting a page - this seems to mostly effect pages where files may be being uploaded while posting a forum message (or replying). Viewing the site pages never has a problem. If I wait 10 minutes, sometimes it goes away - sometimes it doesn't.

When I hit connect, I get a "waiting for...." message, but I never see a page request in my server logs. This only happens on pages I try to SUBMIT, not pages I am reading from.

I have KeepAlive enabled, but set to 2 seconds. There are about 300-400 users on my two forums at any given time.

This was never a problem with Apache1 and RH7.3; is there something obvious I am missing or should be looking at?
