x64

I'm trying to debug an ASP.NET web application in this environment:

Windows Server Standard 2008 SP2 x64
Single-core CPU
4GB RAM
Visual Studio 2008 with Remote Debugger SP1
.NET 3.5 Web Application running in IIS in 64-bit mode

The code I am trying to debug is a simple event handler with some basic sequential code.
What I observe is that breakpoints get randomly ignored and VS often exits debug mode when I try to step through the code. The code is compiled in debug mode.

I've tried all the usual steps: iisreset, reboot VM, rebuild solution, reinstall Visual Studio.

Any ideas?
