Jani.. Im using latest CVS.
Anyway. A bit more of a probe and I have come up with the following
stack trace (Caused when IIS is under heavy load using the script
<?php
for($i = 0; $i < 5000; $i++)
echo microtime();
?>
and doing lots and lots of requests

Havnt particularly looked at this in any depth yet but will do... Back
to critical as IIS is unstable.. although its not critical for all
systems it is for IIS & Windows so its certainly not a show stopper but
needs to be kept in mind and worked on gradually..

Please try using this CVS snapshot:
http://snaps.php.net/php4-latest.tar.gz
For Windows:
http://snaps.php.net/win32/php4-win32-latest.zip
There were some thread-safety issues fixed just recently in CVS so
please try the snapshot.

As normal with these kinda bugs my ISAPI/IIS is rock solid so its very
difficult to track this down. Im moving this bug to critical as it
affects quite a few people. If any of you can compile on your
webservers I would be interested to see if you compile what happens.
Also make sure you always use the latest version of PHP as we are
always fixing Thread Safety issues (To the best of my knowledge this is
probably what is causing this).
Hopefully we can gradually improve performance of the ISAPI extension.
If you have any other information or a short script that seems to cause
it a lot then please add information about it in this bug report.
Also please try unloading extensions from PHP and testing without that
as it might be a thread safety issue in that extension.
Basically until we can get some more concerete information about this
lack of stability its very difficult to track down so anything that may
help is very welcome.

We already had the php4isapi.dll als ISAPI-Filter included, but
nevertheless it does not work at all.
The crashes are gone for sure, but the new flavour ist that
sporadically the connection to an Oracle Database get's lost somehow,
somewhere, and all my scripts do not work anymore.
The problem occures more often after the server has had a heavy load.
Point is: PHP does not crash anymore, but in order to have a working DB
connection I have to restart the iisadmin-service.
regards,
Bernd

I was experiencing this type of crashing over and over myself with
win2k SP2. The solution was to add the ISAPI DLL in the ISAPI Filters
list as well as the App Mappings. After this ISAPI has been rock
solid. This is the same solution as in this bug report:
http://bugs.php.net/bug.php?id=15324 .
Note: I did not do this at first because the PHP Manual specifically
said that I should not do so
(http://www.php.net/manual/en/install.iis.php) unless I needed it for
HTTP Authentication. Maybe someone should place some errata in the
documentation?
