+Status: Feedback
Bug Type: Unknown/Other Function
Operating System: Windows 2003

FCGI works with IIS6 and IIS7, see http://www.iis.net/php
Without a reproduce script, there is no chance to even have a
diagnostic of your crash.

I can't provide a script as the server is full of PHP based websites so
the cause/trigger is unknown.
Yes, but this particular server requires the ISAPI filter.

We need a script as well.
By the way, ever considered fastcgi instead of ISAPI?

Made a mistake in the DebugDiag summary, it is actually:
In w3wp.exe__PID__1652.dmp the assembly instruction at
php5ts!zend_hash_del_key_or_index+10a in \\?\C:\PHP5\php\php5ts.dll from
The PHP Group has caused an access violation exception (0xC0000005) when
trying to write to memory location 0x0003213c on thread 0

Description:
------------
Since upgrading to PHP 5.2.8, one of our servers has started to crash
once or twice a day - I assumed PHP was the cause and DebugDiag points
at PHP too.
I am not sure how to reproduce the crash on demand.
Zend Optimizer isn't enabled, it was the first thing I tried - still
crashes without it.
Reproduce code:
---------------
n/a
Expected result:
----------------
n/a
Actual result:
