Event ID 5197 — IIS Worker Process Dynamic Idle

Applies To: Windows Server 2008 R2

The Internet Information Services (IIS) Worker Process Activation Service (WAS) can dynamically adjust the idle time-out of worker processes based on current load. You can specify the maximum number of worker processes that can run concurrently on a Web server. If the maximum number is reached and dynamic idle is enabled, WAS dynamically reduces the idle time-out. This could allow new worker processes to start sooner and prevent the Web server from becoming unresponsive.
