Jamie,

Your Mac has 8G memory, does not mean your NCL can use all of them.
You may have other program running, such as your dock, web browser,
finder, etc.
For example, I have firefox running, which takes about 150M.

Also, there may be per process limit on your mac, and you may
use "limit" command to see if there is a limit on each process.

Thanks,
