 Operating System: Windows Server 2003 SP2 32bit
 PHP Version:      5.2.2
 New Comment:

I think i got it now. We used Alternative PHP Cache (APC) extension
with PHP. This seems to have problems with multithreading environments.
Allthough the doc doesn't mention it. It runs ok now without APC. If
this was realy the problem, please update the documentation or fix APCs
multithreading ability.

Description:
------------
We got 5.2.2 in win2k3SP2/IIS6 32 Bit.
PHP installed as ISAPI extension, not filter.
Many concurrent application pools.

The problem seems to go away when all webs run in the same application
pool (No multithreading/multiionstanceing). It also occours when there
is only 1 pool with more than one worker (webgarden-configuration). So
there is a point to start.

It's not a real workaround for us, because in the huge production
environment we run, we need to separate the application in safe pools.

Reproduce code:
---------------
Any PHP application, as long as many run simultaneously on different
worker instances. Examples: PHPMyAdmin, Mediawiki, Mantis, ...

Expected result:
----------------
Standard output of the Applications

Actual result:
--------------
No content returned, but
either something like this in the win application eventlog:

Event Type:     Information
Event Source:   Application Error
Event Category: (100)
Event ID:       1004

or, more often, this in the system event log:
