index.php gets send as download request on random occasions...

Hello

We have had a problem with getting "You want to download index.php/viewtopic.php ect" on our website for quite some time now, and been trying to rule out server load ect. Mainly trying that since it seems to happen mostly when the website has alot of visitors

But given that by throttling all apache2 server load settings to lowest minimum, we actually get an appropriate error msg from the server when requesting to view the site we are starting to run out of options and idea's...

It can be provoked to happen by hitting several different links quickly after one another for a minute or so...

The site is behind a proxy and other sites that proxy forwards to work without a problem, however they do run on another VPS!

The VPS is a gentoo-openvz-~x86-2008.11.30 running apache-2.2.15, mysql-5.1.44-r1, php-5.2.12

I would have added screenshoots but this site wont allow that or allow urls for that matter to new users...

The file that phpbb3 sends when getting the error from trying to view a topic on the forum, however this "download file error" happens all over the site, just mostly occurs on the forums since there is usually the most load/people so its seen more often there! Contains this code below:

    HTTP/1.1 200 OK

Any help or suggestions of any kind will be much appreciated!
