ISAPI is deprecated and not maintained anymore. Please try the same script using the FastCGI interface instead (works with IIS5/6/7).
 [2009-09-11 14:52 UTC] matroy at investpsp dot ca
I'm not using it in a web server, it's as a command line using the php.exe.

I've got the same proble with 5.2.6 and trying with 5.2.11RC3...
 [2009-09-11 18:28 UTC] matroy at investpsp dot ca
Same problem with 5.2.11

Tested with 5.2.11, 5.2.10, 5.2.6

I thought it was due to mssql ext. so I've switched to sqlsrv and still go the crash.

loaded extension are:
php_curl.dll
php_mcrypt.dll
php_mysql.dll
php_sockets.dll
php_zip.dll
php_sqlsrv_ts.dll
 [2009-09-12 11:15 UTC] pajoye@php.net
For what I see in the crashlog, it uses ISAPI. To use PHP with IIS, the recommended way is FastCGI (nts build, non thread safe).

If you are using it only in the command line, please use the NTS (non thread safe) as well.

We also need a script to reproduce the crash.

Hello,
I am experiencing quite the same situation though i'm running Apache 2.2 under windows xp sp3. PHP version is 5.3.5.
The weird part of all this is that, right after the installation of PHP, it works fine (no bug), the PHP module interpreting quite well php code. But after rebooting, the apache server fails starting when loading the php module (php5apache2_2.dll) claiming an "application error" due to php5ts.dll module. I installed and uninstalled it twice and each time the same prolem occurred the same way. 
HTTP    : Apache 2.2.17.0
PHP     : 5.3.5.0
Windows : XP SP3

Many things can cause this error message.

We still need a way to reproduce it, a small script.
 [2011-01-11 10:52 UTC] eb at upcl dot univ-lyon1 dot fr
Well, actually, adding a line such as "LoadModule php5_module "C:/HD3/apache_php_mysql/software/php/php5apache2_2.dll" in the configuration file of the apache server is enough to lead it failing to start and issuing a "Application défaillante httpd.exe, version 2.2.17.0, module défaillant php5ts.dll, version 5.3.5.0, adresse de défaillance 0x000e890c." in the windows log file. As I told you, this occurs ONLY after the system has rebooted. Right after the installation, all works well.
 [2011-01-11 14:05 UTC] eb at upcl dot univ-lyon1 dot fr
I modify my php.ini file for it expresses error messages. PHP, on loading, claimed beeing unable to load a few modules though available in the appropriate directory; commenting out the loading of these modules in the php file fixed the problem.
These modules were 
; extension=php_oci8.dll
; extension=php_oci8_11g.dll
; extension=php_pdo_oci.dll
; extension=php_sybase_ct.dll
 [2011-03-08 21:49 UTC] mdurovic at gmail dot com
Same issue it happens around 3-5 times a day apache crashes and recycles. I have around 30K page views per day and I can't pin down what causes the error. Any help would be greatly appreciated.  

PHP: 5.2.17
Appache: 5.2.17
OS: Windows 2003 SP2

PHP.ini:

extension=php_curl.dll
extension=php_gd2.dll
extension=php_mbstring.dll
extension=php_mcrypt.dll
extension=php_mysql.dll

Without a script to reproduce your problem we will have no chance to fix it.

It looks like httpd crashes after this error msg in the event viewer.

PHP Fatal error:  Maximum execution time of 30 seconds exceeded in C:\ftproot\LocalUser\linkmarket\framework\common\php\session.class.php on line 71.

Always the same error.. with 5.3.6 and 5.3.8... :/
 [2011-09-02 14:12 UTC] skys dot dragooon dot adsss at gmail dot com
I solved my problem.
This error occured with php.exe, php-cgi.exe and php-win.exe, and apache's launch..
In my case, it was due to a co-exist of PHP5.2.x and PHP5.3.x version and the bad use by my PHP5.3.x of the PHP5.2.x INI file. (PHPRC environment variable pointing to PHP5.2.x INI that I missed)
