On a multi-processor computer that has a DLL loaded at the 0x33A20000 address space, if you make any request in your Web browser that Microsoft ASP.NET handles, you receive the following error message from ASP.NET in your browser window:
Additionally, you may receive an "HTTP 500 Error" error message in the browser or in the Microsoft Internet Information Services (IIS) event log.
Server Application Unavailable
This behavior occurs if you use the /BASE switch when you compile a DLL in Microsoft Visual Studio .NET and if you have the address location set to 0x33A20000. The DLL is loaded in a process before ASP.NET is invoked and before the associated .dll files and other files are loaded.
Because the 0x33A20000 address space is almost in the middle of the 2-gigabyte (GB) virtual address space, the common language runtime cannot find a clean, contiguous 1-GB space to use for the garbage-collected heaps.
Also, the order that the DLLs are loaded appears to affect this behavior. If the DLL that uses the 0x33A20000 address space is loaded in a process after ASP.NET has been invoked, ASP.NET will continue to work correctly. Although you can rebase the DLL, this may not be a reliable solution for this behavior.
This problem may occur if you use ASP.NET in conjunction with other currently available Microsoft products. For example, if you use Microsoft Content Management Server 2002 (MCMS) sites in the same application pool as ASP.NET, but you visit the MCMS sites first, you will always experience the behavior that the "Symptoms" section describes.
To resolve this problem, install this hotfix on the Web server.
