Application Pool mis-configuration in SharePoint 2010

There is a “small” error in the Application Pool configuration of SP2010:

“Unfortunately when creating a Web Application, SharePoint 2010 uses the SharePoint only property Display Name for the STS application. The STS application is required as part of every SharePoint 2010 Web Application and lives at /_vti_bin/sts.

This will result in a 5048 Warning from WAS within the System Event Log (for each Web Application)”
