  • Re: Who to contact for FastCGI support?

    You should do some analysis on your own and digest what Microsoft replied to you.

    IIS uses FastCGI to call PHP, so it involves IIS itself, the FastCGI module, and PHP's FastCGI host (php-cgi.exe). And Microsoft Product Support Services can only help you on IIS itself, and a little bit of the FastCGI module. If the performance issue (like high CPU usage, and crashes) is caused by PHP FastCGI host, then you are out of luck, and have to resort to the PHP community due to the nature of such an open source project.

    Usually the solution is to upgrade to latest PHP version (such as 7.x).
