Bug description:  php returns no data

sometimes when i click on a link the php-script returns no data, so a blank
page is displayed. this error just happens sometimes. not regular. also
this happens more often when i submit a <form> (doesn't matter if POST
oder GET method).

here an example script (index.php):

<?
include("include/server.php");
include("include/settings.php");

$oPage = new XTemplate ("html/root.html");

switch ($what) {
        case "ha":              $sTitel =       "home &amp; aktuelles";                
                                                                                       
                          $sInhalt
=       include("news.php");            break;
        case "lpp_p":   $sTitel =       "leistungen preise &amp; produkte -
printlayout";                                                                          
 $sInhalt =      include("lpp_p.php");           break;
        case "lpp_sp":  $sTitel =       "leistungen preise &amp; produkte -
spieleprogrammierung";                                                          
$sInhalt =      include("lpp_sp.php");          break;
        case "lpp_wh":  $sTitel =       "leistungen preise &amp; produkte -
webhosting";                                                                           
 $sInhalt =      include("lpp_wh.php");          break;
        case "lpp_ipm": $sTitel =       "leistungen preise &amp; produkte - internet
projekt &amp; beteiligungs management"; $sInhalt
=       include("lpp_ipm.php");         break;
        case "lpp_ssn": $sTitel =       "leistungen preise &amp; produkte - software,
server &amp; netzwerktechnik";                  $sInhalt
=       include("lpp_ssn.php");         break;
        case "lpp_os":  $sTitel =       "leistungen preise &amp; produkte - online
shop";                                                                          
$sInhalt =      include("lpp_os.php");          break;
        case "lpp_ie":  $sTitel =       "leistungen preise &amp; produkte - internet
entwicklung";                                                           $sInhalt =     
 include("lpp_ie.php");          break;
        default:                $sTitel =       "home &amp; aktuelles";                
                                                                                       
                          $sInhalt
=       include("news.php");            break;
}

if ($what == "ha" || !$what) {
        if (!$show) {
                $oPage->parse("root.fragen");
        }
}

$oPage->assign("FILE",          $PHP_SELF);
$oPage->assign("TITEL",         $sTitel);
$oPage->assign("INHALT",        $sInhalt);

$oPage->parse("root");
$oPage->out("root");
?>

the file "server.php" just checks on which server the script is running an
sets the include_path and global mysql-access variables. and it includes 5
more php files which contains classes and functions.

the file "settings.php" has the following content:
<?
set_time_limit(0);

header ("Expires: Mon, 26 Jul 1997 05:00:00 GMT");
header ("Last-Modified: " . gmdate ("D, d M Y H:i:s") . " GMT"); 
header ("Cache-Control: no-cache, must-revalidate");
header ("Pragma: no-cache");

session_register("sLanguage");
?>

when i remove the header-data the problem still exists.

also i tried the following in my "index.php"

<?
include("include/server.php");
include("include/settings.php");
?>
<div></div>
<?
$oPage = new XTemplate ("html/root.html");

if ($what == "ha" || !$what) {
        if (!$show) {
                $oPage->parse("root.fragen");
        }
}

$oPage->assign("FILE",          $PHP_SELF);
$oPage->assign("TITEL",         $sTitel);
$oPage->assign("INHALT",        $sInhalt);

$oPage->parse("root");
$oPage->out("root");
?>

the problem still exists ...

i use apache 1.3.26.
