Servlet has thrown exception:javax.servlet.ServletException: Timed out

Only this week (app.) I am getting the following error when trying to
validate my site...

> Servlet has thrown exception:javax.servlet.ServletException: Timed out


The site is... http://wow-factor.com
This site has a gzipped .php CSS file that has been passed CSS validation
for the last 12 months at least and is only now throwing up this "servlet"
error.
Further details on this method of compressing your CSS is detailed here....

The header of my CSS file is....

> <?php
> ob_start ("ob_gzhandler");
> header("Content-type: text/css; charset: UTF-8");
> header("Cache-Control: must-revalidate");
> $offset = 60 * 60 ;
> $ExpStr = "Expires: " .
> gmdate("D, d M Y H:i:s",
> time() + $offset) . " GMT";
> header($ExpStr);
> ?>

> @import url(css/forms.css);    /* Import default form styles */
> @import url(css/comments.css);    /* Import default comment styles */

I'm just wondering ... what changed and if there is something I can do about
it.?

Cheers

John
