We are nowhere on this issue. I should add that with OpenQwaq / 
Teleplace we've been running large images (300-500MB) all the time on 
Windows with no problems. And I am not at all convinced that this is 
even a VM issue; I find it more likely that there might be some platform 
dependency that causes some code to go wrong and actually eat all 
available memory. My comment below was just pointing out that your OS 
memory configuration looks perfectly normal.

What I would do in your situation is to run the code that created this 
image directly under Windows, then save and try to start it up again. If 
you get an error when you run the code, you will be able to tell whether 
it's a memory problem or not. If the image saves and starts fine again 
on Windows, you can be pretty sure that it's not a VM problem but some 
platform dependency. And then you might try to move the image to a Mac 
to see if that teaches you anything.
