We have installed a Joomla 2.5 website in IIS8 with the support of FastCGI, there are times that the Joomla website cannot be open, and the fastcgi.exe processes hangs up.

When the joomla website hangs up I cannot also open a simple php file like sample.php that contain a code to display date and time, but static file such as sample.html is opening.

The problem persist after 7-14 days or sometimes when we have a huge amount of traffic the problem will come immediately.

Is there any settings that I missed in PHP
