I'm actually working on a mac, so that shouldn't be the problem.
So your proposition to use -mmap would be unix specific? Is the option 
available on mac?

I don't have a Mac, but you can easily check it by starting an image with "-mmap 64m", then allocating a 64MB array in the image. If it fails, then the switch works, otherwise not.

The unix VM and apparently also the Mac VM has an option -memory that allows 
you to set a heap size:

[adrian:/Applications/Squeak 4.2.3beta1U.app/Contents/MacOS] ./Squeak\ VM\ Opt 
-help
Usage: ./Squeak VM Opt [<option>...] [<imageName> [<argument>...]]
     ./Squeak VM Opt [<option>...] -- [<argument>...]

Common <option>s:
-help                 print this help message, then exit
-memory <size>[mk]    use fixed heap size (added to image size)
-pathenc <enc>        set encoding for pathnames (default: macintosh)
-headless             run in headless (no window) mode (default: false)

Notes:
<imageName> defaults to `Squeak.image'.
If `-memory' is not specified then the heap will grow dynamically.
<argument>s are ignored, but are processed by the Squeak image.
The first <argument> normally names a Squeak `script' to execute.
Precede <arguments> by `--' to use default image.

This is ok for Mac, but the unix VM takes different arguments.

Hi

I'm having trouble with low space warnings in Pharo. Is there a source on how 
much memory the image can get from the OS? Is there maybe a way to up that 
limit? I am loading a lot of data into the image and the limit at the moment 
seems to be around 500 MB.

Thanks for any ideas.

Cheers,
Max
