Is this the shortest?? Try to weed out lines until it doesn't crash anymore, because your script is a bit too long to check, and it's not self-containing either, it won't run because of parse errors and missing includes. YOu say it's because of DB access, try to do the specific queries only, and nothing else.

It just crashes on my home pc with amd-cpu. I also put the script online (Linuxbox, Kernel 2.2.16, mod_php-4 (4.0.6), Apache/1.3.19 (Unix) (SuSE/Linux), MySQL 3.23.43 ,and there it runs perfectly: Here is the script: ===================================================== <?php //// Version 0.1 //// hcms_fe_engine.php //// ( Frontendengine ) //// Gibt den Inhalt der Site für WebUser aus ///////////////////////////////////////////////////////////// // Sessionverwaltung einbinden include ('hcms_fe_session.php'); // Allgemeine Konfiguration einbinden include('hcms.init.php'); // Datenbankschnittstelle einbinden include ('hcms_smod_db.php'); // FE-Funktionen einbinden include('hcms_fe_functions.php'); // Site-Konfiguration aus DB holen $sConfig = getSiteConfig(); // Überprüfen, ob Site online ist if ($sConfig[online] == "n") { header("Location: hcms_fe_siteoffline.html"); // Ausweichdokument anzeigen } // Site ist online else { // Prüfung ob GenTime gewünscht if ($sConfig[showgentime] === "y") { // Start der Erstellungsdauer $timer = new cGenTime; $timer->start(); } /// ENDE Prüfung GenTime gewünscht //////// // // Seiten-Code erzeugen // //////// if (!isset($location)) { $location = 1; } /// Seitenkopf generieren echo("<html><head><title>$sConfig[sitename]</title></head><body bgcolor=\"#999966\">"); include('layouts/site.css'); // Main-Layout-Tabelle generieren echo ("<center> <table class=bodytab cellpadding=0 cellspacing=0 border=0 width=800>"); echo ("<tr><td colspan=3 height=81><img src=\"".$IMG_SITE."logo_head.png\" border=0 width=800></td></tr>"); echo("<tr><td colspan=3 height=10 valign=top width=800>"); // Main-Menu aus DB holen $mmenu = generate_menu(1,$location); echo("<table cellspacing=0 cellpadding=0 border=0 width=\"800\"> <tr><td class=conmenu>&nbsp;&nbsp;");^ for ($i = 1; $i <= count($mmenu) - 1; $i++) { echo("$mmenu[$i]&nbsp;&nbsp;|&nbsp;"); } ^^^^^^^^^^^^^^^^^^^^^^^^ This is the part that crashes under Win2k....
