While executed by IIS, php.exe remians in Tasklist with CPU usage 0. The browser output is nothing for long long time. No timeout even!!

I've provided all required permissions to root php folder and child object.

I switched to using php5isapi.dll. (I reinstalled without 'CLI Executable' option.)

It works fine only for phpinfo(); Running the application gave one more issue.
==============================================
Out of process application '/LM/W3SVC/1/Root/drupal' terminated unexpectedly. 
==============================================

Every request gives Internal Server 500 error and then on second try it returns resulted page or empty output.

Thanks Help is needed urgently.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32

Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.

Hi,

Can you help me get the debug information as per your requirement?

Steps done by me.
1] Installed the VS (Also VS.NET 2003)
2] Initiated request to php page.
3] waited long time, but no reply.
4] Opened Tasklist, Right clicked "php.exe" and clicked Debug.
5] MSVC opens. 
6] Problem is the debug code is not getting attached to the php.exe.
I'm getting "'D:\php\php.exe' does not contain debugging information."

I'm stuck here.
==========================================
I've few screenshots, how can I send them to you?
Screenshots shows message stating "The process appears to be deadlocked (or is not running any user-mode code). All threads have been stopped." 
Steps to regenerate.
1] Start VS.NET 2003
2] Request the php page on IIS.
3] Attach php.exe for debugging in VS.NET
4] click on Break button.

Please report problems related to PECL extensions using PECL bug tracking system.
It's not PHP problem, but a problem of particular PECL module, which has been unsupported for years.

Code is compiled with the following options.

cscript /nologo configure.js --enable-debug-pack --with-php-build=D:\php_build\ --without-libxml

I started the debug of php.exe in MSVC. Argument given was a file with content "<?php phpinfo();"

I've not installed any of PELC options.

1] Request php page from browser.
2] wait for sometime for any output.
3] Open TaskList.
4] Right click Php.exe and Debug.
5] In MSVC, Break the execution.

Above are the steps to get the output as below in the call stack.

The above reply at "[16 Nov 12:14pm UTC] jitudavda at hotmail dot com" is done after chanding installation without any extension & extras.

CHANDING THE STATUS TO BOGUS HURTS.
PHP version has bug with WinXp, this is a fact.
I expect the bug manager/moderators to help in finding the place, instead of making the issue as bogus. 

If you need further help, please write here for the step you need me to perform. 

Below is the current installation of php on WinXP.

OS: WinXP
PHP: php 5.2.0
INSTALLATION OPTIONS: 
   1] \PHP\Program\CLI Executable
   2] \PHP\Web Server Setup\IIS 4+ ISAPI module
   Note: All other options are not installed or marked "donot install"

PERMISSION: IUSER_DEV has Read/Execute permision on all object of "D:\PHP" <-installed folder.

PROBLEM: Request to any php page hangs the php.exe

Goodluck.

Please find & delete all php.ini's in your system.
After that make sure you don't have any .dlls from the previous PHP version installed, delete them if you find any.
Then grab the latest snapshot, install it and run `php.exe -v` and `php.exe -m`.
If you're still able to reproduce the problem with this two simple commands - please post *REAL* backtrace (the one that doesn't mention modules which are not installed).
Thank in advance.

If php.exe hangs when you request a page through ISS you are configuring IIS wrong!

php.exe => CLI version of PHP
php-cgi.exe => CGI/FastCGI version
php5isapi.dll => ISAPI version.

php.exe should only be used for command line execution of PHP scripts.

==1] ==========================================
- php.ini files from windows folder and D drive are removed.
- uninstalled php
- remove all the folders and files from the folder D:\PHP
- reinstalled the php with only two options selected.
- IIS Restarted.

POINT 2 AND 3 HAS THE SAME BEHAVIOUR.

Point 2 has the installer versions of php.exe and php5ts.dll
Point 3 has the local compiled versions of php.exe and php5ts.dll. 

Note: 
- Compilation is done with all instructions from PHP team. No edit at any places.
- Compilation of php.exe gives the same size of php.exe
- Compilation of php5ts.dll is reduced size. 
----Installer version php5ts.dll [4589 KB]
----Compiled version php5ts.dll [2693 KB]
----Compiled version of php5ts.pdb [4169 KB]


Please ask for any further help from me.

Thank  you.

How did you configure IIS to use php.exe instead of php-cgi.exe and why?

I've not done any configuration of php with IIS. It's done by the installer itself.

I'm now testing with the IIS configuration as noted above.
- Use ISAPI version.

Though it had the similar issue earler. I will get back soon with the results.

Thanks

-Uninstalled PHP.
-Removed configuration from IIS
-Installed PHP
-Added configuration for ISAPI dll.
-IIS reset
1] Done request for php page.
2] Got the output as expected.

I feel the wrong configuration of IIS is the issue here. But see correct configuration was done by me and I'd the same issue. Check the second post at "[11 Nov 4:58pm UTC] "

Now I will install the ext modules and perform the same test. May be the problem caused by ext modules only.

I will reply here after testing with ext modules.

Please give me the ext module bug reporting url.

Thank you for all help.

Yes, it works with ext modules. I installed on mysql, mssql, pop and smtp.

It works fine right now. Threads module is not installed.

Not a PHP problem in the first place.
