运行PHP脚本90秒后内部服务器错误500

Question

have a php script that runs for a few minutes. It creates a lot (up to 10000) of small (2-20K) files on the server.

For some reason, after approximately 90 seconds, I always get a 500 Internal Server Error. I thought it might be some php.ini problem, so I edited some values there:

max_execution_time = 1000
max_input_time = 1000
default_socket_timeout = 1000
memory_limit = 400M
post_max_size = 100M
file_uploads = On
upload_max_filesize = 100M

I also checked to see if these new settings occurred by using phpinfo(), and have seen that they did take effect.

What else can I do/change in order to make my script work?

PHP5.5 Windows Server 2008 R2, SP1, Unfortunately, only 600 MB of physical memory Nothing in errors_log.

In hope to save other people's hair (I pulled out pretty much of my own on this one)

The solution is to increase the FastCGI activity timeout.
Use appcmd, the IIS 7 command line tool, to modify the IIS configuration XML file.

Run cmd in an administrator mode.

To check the current settings use:

%windir%\system32\inetsrv\appcmd list config -section:system.webServer/fastCgi

To add the activity timeout (assuming CGI location is C:\php\php-cgi.exe):

%windir%\system32\inetsrv\appcmd set config -section:system.webServer/fastCgi /[fullPath='C:\php\php-cgi.exe'].activityTimeout:600

This output now should be similar to this: -

<system.webServer>
<fastCgi>
<application fullPath="C:\PHP\php-cgi.exe" activityTimeout="600" instanceMaxRequests="10000">
<environmentVariables>
<environmentVariable name="PHP_FCGI_MAX_REQUESTS" value="10000" />
</environmentVariables>
</application>
</fastCgi>
</system.webServer>
