.Net Application Restarts Frequently on Windows Server 2003

While stress testing a .Net 2.0 application, we noticed the application was restarting about every minute. This restart did not occur under normal loading, but when we really pounded the app it did this weird restart every minute thing.

The application ShutdownReason was "Configuration change", a more detailed message:

_shutDownMessage=Overwhelming Change Notification in c:\inetpub\wwwroot
Overwhelming Change Notification in C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\Config
CONFIG change

This happened on Windows Server 2003, but not on XP.
The solution was to install the Microsoft .NET Framework 2.0 Service Pack 1. Now it is happy.
