Performance Profiling: IIS crashes

yogui

I'm profiling an ASP.NET app for performance on a W2003 Server, IIS 6. I have tried setting the web site to run in IIS 5 isolation mode.

The profiling stops when IIS stops responding.

The following events are loged when the crash occurs:

Event Type: Error
Event Source: .NET Runtime
Event Category: None
Event ID: 1023
Date: 7/27/2006
Time: 10:28:27 AM
Description:

Event Type: Error
