System.ArgumentOutOfRangeException or CouldNotMapFileException errors in Memory Profiler 5
Category: Troubleshooting & error messages
Date: 02 Feb 2011
Product: ANTS Memory Profiler
This appears to be an issue caused by a bug in the .NET profiling interface. Some of the int32 arrays being allocated are not being reported by .NET as objects to the profiler, although the objects that reference them are (and are apparently still valid as objects and not candidates for garbage collection).
What we have found is that it works to disable the server garbage collector as described here: http://support.microsoft.com/kb/911716
Remember- "server GC" actually means multi-core GC.
