Hi Ben,
At my application I am uploading with a selfwritten plug-in the whole  
stack (all nearly 300 images). It is necessary to get the z-values  
out of each image corresponding to the points of the other images.  
Therefore I had to increase the 'memory & threads' option. But image  
works only till 2100MB, if I want to use more, ImageJ doesn´t start  
anymore. Inside of a 32bit-Linux distribution like Fedoracore 5 I  
could use around 2750MB.
A friend told me, that could be an answer inside of the kernel  
structure of the mac-osX. But I am not that familiar and started  
yesterday my search for solutions at the apple-developers website.

Cheers,
Thoralf.

Hi,

This is a little off topic, but I am wondering why a Virtual Stack  
requires the same amount of memory as a regular stack?  I thought the  
purpose of the Virtual Stack is to have only one image in RAM at a  
time and thus reduce the RAM requirements -  all other images in the  
stack would reside on disk (or where ever).  Perhaps I have that  
wrong and if so would love to get some clarity on this issue.  I have  
been alerted by a user that one of my plugins that uses stacks is  
bumping up against memory issues so I am keen to come up with a  
workable fix.

Cheers,
Ben
