Description:
------------
I posted my problems two months ago at bug report nr. 24534:
http://bugs.php.net/bug.php?id=24534
But I wasn't the original submitter so I opened a new report.

I actually use the latest version of PHP, but the problem still exists.

The manufacturer of the server checked the hardware - says the hardware is ok.
I used DebugIIS and was sending the dump to Microsoft. They say it is a PHP problem - in no case IIS or hardware.

They gave me the following analysis:

Access violation - code c0000005 (!!! second chance !!!)

Use of ISAPI PHP is not recommended as it is known to have problems, as you have discovered.

We are interested in fixing the problem, but it is difficult.  I'll see if I can arrange a snapshot that includes debug symbols for you to try and get a stack-trace.

If a solution can't be found quickly enough for you, you might have better luck using PHP configured as FastCGI or CGI.

We are aware of PHP's problems with stability under IIS and are working 
to rectify the problem. Unfortunatly your bug report does not contain any
extra useful information and we already have enough bug reports open about
this issue. If you can provide more detailed information such as a 
reproducable crash or a backtrace please do so and reopen this bug. 
Otherwise please keep trying new releases as we are working to resolve 
the problems on this platform
 
Thanks for your interest in PHP.
