php-cgi.exe process on IIS
- by HYP
The production server runs a PHP application on IIS 6.0. During the peak hours we have had a few issues where the php-cgi.exe processes increase in numbers and approach around 200. The server comes to a crawl and we have to restart the server a multiple times to restore the normal behavior. When the server is running normally, I have noticed that there are only 10-15 php-cgi.exe processes in the task manager.
What could be causing the php-cgi.exe processes to increase in number from 10-15 to around 200 during the peak hours? Where should I look for a cause?
