iis and php max execution time error

Question

First of all I'm running a VPS with Windows 2003 Server with IIS 6.0 and Plesk

These are the settings from php.ini max_execution_time = 300 ; Maximum execution time of each script, in seconds

The returned value is ok echo ini_get('max_execution_time'); // 300

But when I'm trying to use the keygenerator it stops executing after 30 seconds and shows Fatal error: Maximum execution time of 30 seconds exceeded in ... on line 475

The generator works just fine on a shared hosting but it doesn't work at all on my vps...

I even tried using set_time_limit(0);

Still the same.. I have FastCGI installed and the VPS is a QuadCore Xenon (with 512mb ram) so It really can't be a issue of performance

Solution

FastCGI has a limit for a request timeout in %systemroot%\system32\inetsrv\fcgiext.ini:

; RequestTimeout=n
; - Specifies the maximum allowed time, in seconds, for a request to this
;   application.  If a FastCGI process takes longer than this amount of time
;   on a single request, it will be terminated.  If not specified, the default
;   value is 90 seconds.

See if this value is set, or needs to be increased.

The limit in the IIS console tends to refer to ASP pages - things it processes itself, internally, rather than passing to an ISAPI filter.

In IIS manager (7.0), you can double click FastCGI, and then double click PHP-CGI.EXE to exit this value. After that, restart the server from IIS manager

BTW Also check the Advanced settings of the Application Pool under which the Applications are running.
