This happens under some type of load on the IIS web server protected by the RSA agent, either with a load running stress test or with the SharePoint Web Crawler.

Server performance is heavily impacted by this and SharePoint sites are unavailable due to Application Pools stopping

Task

1. Configure the Application Pool for your [SharePoint] Web Site to limit CPU utilization (CPU throttling)
2. Run an iisreset.

Resolution

Configure the Application Pool for your [SharePoint] Web Site to limit CPU utilization (CPU throttling)

1. Follow Microsoft TechNet video for reference, but basically, go to Application Pools in IIS
2. Find the site's App Pool  and select Advanced Settings.

3. Set the CPU limit in 1/1000s %.  For example, 30000 = 30% of CPUs, then under Limit Action use the dropdown to change from No Action to KillW3wp
4. Run an iisreset.
