You are loading a 3D volume 3 times? You definitely do not need to do
that for visualization.

The problem is not swap/pagefile. It is that under 32 bit windows
(without /LARGEADDRESSAWARE and the /3GB switch) you have a 2GB
address space maximum regardless of the amount of ram or swap that you
have. Inside this 2GB address space dlls that are needed in your
application will fragment this 2GB such that ~1.2GB is the largest
single block of address space available.
