php-cgi.exe is opening up an enormous amount of instances

Question

I am hosting php 5.2 on IIS 8. Yes, I know that's a horrible idea, but that is reality.

The server runs out of resources after our website is up for a few hours because for some reason php-cgi.exe opens up dozens of times:

enter image description here

What am I doing wrong? perhaps something wrong with the php.ini file?

Could this be caused by mssql_result not closing the connection?

I have actually been able to limit the number of instances, but then all additional requests are getting processed very slowly.

It's either in ApplicationHost.config or in Web.config at the directory level. — AbsoluteƵERØ, Mar 29 '13 at 23:00
@cpattersonv1 im sorry which directory? although we're running on IIS, this is not a .NET application. i've searched for "config" in the entire website directory structure and wasnt there — Alex Gordon, Mar 29 '13 at 23:05

Did you ever resolve this? We are having the same issue and the cause of the rampant number of processes occurs when we are hit by a search bot. In our case, the php run, we actually want to be trolled by the bot, but yeah, it stalls IIS every time. I've messed with various values of MaxRequests, Max Instances, PHP_FCGI_MAX_REQUESTS but not getting anywhere... php 5.6.1 on 2012svr — , Apr 14 '16 at 15:58

I think it's better for you to perform the installation automatically using the tools provided by Microsoft:
