I too can replicate it on both the 5.2-devel (the current) and 5.1.4.
This is becoming a very irritating problems as w3wp.exe keeps crashing.


Windows 2003 SP1 running IIS 6 with PHP ISAPI.

We tested the 5.2 snap on two of our Windows 2003 SP1 servers, and the
aforementioned crashes occur with more frequency than with PHP 5.1.4 on
the same servers.

I came up with exact the same crash analysis, even with the latest PHP
snapshot 5.2.0-dev dated May 28 2006 00:17:10:

It is weird, that at the moment of crash sometimes there is NO ACTIVITY
(= noone is browsing the page).
On the other hand, w3swc.exe process consumes too much CPU time,
compared to my observations from some time ago, when WebAppPools did
not crash.
The observed WebAppPool is isolated, I mean, only 1 web uses this pool.

I have exactly the same problem.

Since i am on a production server, i can't install MSVC6. (it seems to
be replace with MSvisual express2005, which require to remove all sql
server prior to 2005. And i can't remove it on production.)
I try to add the .pdb to the DebugDiag symbol path but the file doesn't
match the dll. 

Is this because the debug pack is for php5.2.x?
Do i have to install php5.2.x-dev?
Where can i find the debug pack for php5.1.4?

I would be happy to help, but i don't know how to produce the backtrace
you require.
