Could not map a view into memory

[dmd1214]

Things have been going great for a few days of memory analysis, but i'm getting this error when saving results now.


Could not map a view into memory.

Caused by:

I think this is the log file you need:

I believe this is another manifestation of the .NET bug that also results in ArgumentOutOfRangeExceptions - see http://www.red-gate.com/messageboard/viewtopic.php?t=9421 for a discussion.

The solution should be the same - follow the steps here http://support.microsoft.com/kb/911716 to switch your ASP.NET application to use workstation GC.

Thanks Andrew. Things have been going fine since I made that change... I'm a little curious why a windows server 2003 fix (as the MS link indicated) worked for me... but as long as it works, I'm happy.
