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:
--------------
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 0x00000000 on thread 0

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

We need a script as well.

By the way, ever considered fastcgi instead of ISAPI?
 [2008-12-28 11:09 UTC] w dot ashcroft at redfoxuk dot com 
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.
 [2008-12-28 12:20 UTC] pajoye@php.net 
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.
 [2008-12-29 03:41 UTC] w dot ashcroft at redfoxuk dot com 
Doesn't the backtrace provide any clues?
 [2008-12-29 11:06 UTC] pajoye@php.net 
No, it does not, this is a very common place, called by almost every single script. But it will when we have a reproduce script.
