IIS7 -FastCGI -PHP White Screen of Death

gusus — Sat, 07 Mar 2009 04:59:00 GMT

I am having an issue with IIS7 and PHP relating to clients receiving the white screen of death (blank page) after 90 seconds of processing. Standard php processing works fine.

The following are set in php.ini:

max_execution_time = 180
max_input_time = 180
memory_limit = 128M

In the FastCGI configuration on IIS I have the following:

ActivityTimeout 900
IdleTimeout 300
RequestTimeout 500

I have a simple page that runs through loop and sleeps every 15 seconds. If I set the max_execution_time to 30 seconds, I get the php execution time exceeded error as I should with two entries in the page. If I manually set_time_limit(0), it gives the white page of death. I have set php logging and nothing appears in the log. I intentionally put a syntax error to make sure and the syntax error was logged. In addition, I can set the ActivityTimeout to 10 and IIS gives me a 500 error telling me that the FastCGI process exceeded the configuration activity timeout.

The weird thing is the Failed Request Tracking show that the time taken was 30592 msec with a status of 200 (I assume success). However, the last entry in the request trace is "FASTCGI_WAITING_FOR_RESPONSE"...

Any ideas???

IMPORTANT: PHP scripts are not working due to a Windows Actualization ???

Hi everybody, i have a testing environment to prove web applications developed with PHP5 via IIS7. This environment was configured following instructions in the link http://learn.iis.net/page.aspx/246/using-fastcgi-to-host-php-applications-on-iis-70 and it worked fine.

The problem is that nowadays is not working and i've tried to configure others environment using the link shown before and it does not work either. All requests that i try throws the following error:

HTTP Error 500.0 - Internal Server Error

c:\php\php-cgi.exe - The FastCGI process exited unexpectedly

Could it be a bug or issue due to a windows actualization? it is the only different thing that it has been installed recently in these environment. I found this situation today Saturday 10-25-2008 and i have recieved comments from other persons that are starting to have the same problem.

I tested this case in Windows Vista SP1 x86 and x64, Windows Server 2008.

Thanks in advanced.

Hi,

I am trying to run PHP via FastCGI on a Windows 2008 server. I followed this installation doc http://learn.iis.net/page.aspx/246/using-fastcgi-to-host-php-applications-on-iis7/ and have checked I completed the steps correclty numerous times. However when I try to execute a php page i am presented with the following error:

HTTP Error 500.0 - Internal Server Error
C:\PHP\php-cgi.exe - The FastCGI process exited unexpectedly

Detailed Error Information

Module: FastCgiModule
Notification: ExecuteRequestHandler
Handler: PHP via FastCGI
Error Code: 0x000000ff
Requested URL: localhost/test.php
Physical Path: C:\inetpub\wwwroot\test.php
Logon Method: Negotiate
Logon User: Domain\user

I had PHP working correctly without using FastCGI so im fairly sure its not the PHP installation. The only help i have found on this error is here http://blogs.iis.net/rickjames/archive/2007/10/16/fastcgi-debugging-quot-the-fastcgi-process-exited-unexpectedly-quot.aspx and as I am a novice at debugging something like this im not finding it much help.

I have changed the applictaionhost.config file locking down most sections as this server wiil be used for hosting, but i have doubled checked that the sites attempting to run php have access to all the modules and handlers they require i.e. the FastCGI handler shown above in the detailed error information.

Any ideas on why this error may be happening, or any simple tips for debugging it?

I am thinking a fresh install may be my only way of fixing this?

*****Update*****

After reading other posts I followed these steps mentioned by ruslany

"A possible way to isolate the problem is by running your script from the command line:

C:\php\php-cgi.exe C:\inetpub\wwwroot\phpinfo.php

If you get the same error then you will know that the error has nothing to do with web server or FastCGI module.

Another thing to try is to switch php handler mapping from FastCGI to CGI and see if the error goes away. This way you will know that the error is caused by FastCGI."

So I ran the script from the command line and it returned:

-----------------------------------------------------------------------------------

PHP Warning: PHP Startup: Unable to load dynamic library 'C:\Program Files (x86)\PHP\ext\php_gd.dll' - The specified module could not be found. in Unknown on line 0

Hello World!

----------------------------------------------------------------------------------

I then switched the php handler from FastCGI to CGI and tried my php page using IE which returned the "Hello World" text followed by the php warning above

So, bar the warning it appears to be working correctly. I dont think this warning is crashing FastCGI, however ill work on fixing it just to make sure.
