11865	Somethimes xml response instead of html	icns		"Hi,

We have a problem with our website. Sometimes for no reason we get text/xml responses instead of text/html. We have installed an clean wodpress 2.9.1 version and activated permalinks and created a few pages. Even here the problem exists. When we click around in safari/chrome/ie8 we get sometimes xml responses. Our site is available at http://test.jitscale.com 

There are 2 application servers with an haproxy loadbalancer and a mysql dbserver. The website is shared over the appservers by a nfs share. 

The problem mentioned below:

For example:
