No ideas I really need help with this!

I'm at a total loss for how to resolve a problem I've been having. I've got a fresh Windows 2008 R2 Standard 64-Bit server running IIS7 with the following: PHP 5.3.2 (x64) - (running as a FastCGIModule - php-cgi.exe) MySQL 5.1.45-community (x64) I previously ran the same sites (a shopping cart system and vBulletin) on a Windows2000/IIS5 server with older versions of PHP and MySQL with no problems. Since updating to this new server hardware/software, I'm getting periodic APPLICATION POOL shutdowns. Each of my PHP sites runs in it's own "classic" application pool, so they generally don't both shut down at the same time. I had them both in the same application pool for a while and they would both shut down at the same time under that configuration. The problem manifests itself first with this error: "A process serving application pool 'PoolName' suffered a fatal communication error with the Windows Process Activation Service. The process id was '3368'. The data field contains the error number." And then with this error (when the actual application pool shuts down until I manually restart it): Application pool 'PoolName' is being automatically disabled due to a series of failures in the process(es) serving that application pool. When this happens I get a 503 error returned to any visitors to the website until I notice it and get the application pool restarted. This PHP BUG REPORT (http://bugs.php.net/bug.php?id=47077&edit=2) seems to be related, and I've posted in that to see if I can find some answers...but I'm really at my wits end with this because I'm just not up on this stuff enough to know how to proceed. Here is my PHP.INI file (cleaned up to just the settings, some private info altered): If anyone has any ideas about how I can resolve this problem...I WOULD GREATLY APPRECIATE IT!!! I will answer any questions I can about the server configuration, try anything I need to provided I can figure out how to do it (I've tried playing with the Microsoft Debug Diagnostic v1.1 tool but can't make it do anything useful), etc. THANK YOU VERY MUCH IN ADVANCE!!!
