Description:
------------
The problem is that pages randomly goto a blank screen.  You can go about 5 or 6 pages before it does it.  I checked my logs after one of these bugs occurred and it doesn't show up   at all.  Refreshing the page or copying and pasting the url into the url box gets you to the page after one of these bugs, it's just really annoying to have to do that.  Even pages that only have 1 result returned do this so it's not a memory/cpu usage problem.

I'm using 1and1.com for hosting, they use Apache 1.3.29 and MySQL 4.0.20.  I never had this problem when I was hosting it on my own server but that was with an older version of PHP.

List of modules compiled with PHP (taken from a phpinfo() call):

'../configure' '--with-mysql=/usr' '--with-zlib' '--enable-debug=no' '--enable-safe-mode=no' '--enable-discard-path=no' '--with-gd=/usr' '--with-png-dir=/usr/lib' '--enable-track-vars' '--with-db' '--with-gdbm' '--enable-force-cgi-redirect' '--with-ttf=/usr/' '--enable-ftp' '--with-mcrypt' '--enable-dbase' '--enable-memory-limit' '--enable-calendar' '--enable-wddx' '--with-jpeg-dir=/usr/src/kundenserver/jpeg-6b' '--enable-bcmath' '--enable-gd-imgstrttf' '--enable-shmop' '--enable-mhash' '--with-mhash=/usr/src/kundenserver/mhash-0.8.9/' '--with-openssl' '--enable-xslt' '--with-xslt-sablot' '--with-dom' '--with-dom-xslt' '--with-dom-exslt' '--with-imap' '--with-curl' '--with-iconv=/usr/local' '--with-freetype-dir=/usr/include/freetype2' '--with-bz2' '--with-gettext' '--enable-exif' '--with-idn'

Reproduce code:
---------------
Anywhere on www.jarredcapellman.com (my site) after a couple page views you will see the problem.  At the bottom of page lists the number queries, execution time and memory usage, which aren't ever very high even with quite a few people on it.

Actual result:
--------------
Random blank pages

I can do the same bug as well. I have Server: Apache/2.0.51 (Fedora). it is hard to show you cause it is not a specific function of php that is doing it, that I have seen. I can only get it to do it in IE 6.0. no other browser will do it. so tha tmay mean a IE bug. but it just started recently. if you go to http://www.boxedart.org/phpshop/shop.php/view/0/7/66/allon 

and add 2 products to the cart. close the popup. then in the same IE window, add this url.

http://www.boxedart.com/phpshop/cart_pop.php?action=viewcart&ext=

than if it loads, click in the address field and hit enter. do that until it comes up blank. never hit refresh. if you get a blank screen keep repeating. eventually it comes back.

A couple weeks ago I turned off "cloaking" on ZoneEdit so my pages would show up as http://www.jarredcapellman.com/index.php as opposed to http://www.jarredcapellman.com.

As soon as I turned it off the random blank pages went away.  Maybe the "cloaking" was messing up the way PHP gets variable arguments from a url or something?

If that affects it it's definitely not a PHP bug.
