New Comment:
I used DebugIIS to create a dump and send the files to Microsoft. They
say the reason is the bad PHP code - in no way hardware or IIS. They
give me the following analyses:
Access violation - code c0000005 (!!! second chance !!!)

If the problem is due to a memory shortfall try the following test.
Make a simple php test script and then using ApacheBench or httpref try
sending a large number of requests to it. Meanwhile monitor the memory
usage to see if it continues to increase until eventually there is no
memory avaliable.

One of my customers has the same problem since upgrade from Php 4.1 to
4.32. The error occures 3 - 10 times a day.
I've tried a lot: Installing Php on three different machines with a
clean OS (and different Php versions > 4.2), playing arround with
IIS-settings, enable and disable Zend-Optimizer.
But problem is still there.
Now I use Windows 2003 Webserver Edition. IIS doesn't restart abnormal
(because he now uses a seperate worker process), but in the
Event-Viewer I found this (once again 3 - 10 times a day):
A process serving application pool 'DefaultAppPool' terminated
unexpectly. The process id was '...'.
The process exit code was '0xc0000005'.
When this error occures the following message is displayed on browser:
"Php has encountered an access violation at..."
When I reload the site everything works fine.

So far the snapshot didn't help. IIS keeps resetting (1-2 times a
day).
BUT : I found out, that before it happens, the available System Memory
goes rapidly down. Does this information help in any way?

And make sure you remove ALL existing PHP related dlls/binaries from
your system before installing the new version.
