Hi Rich-

That's IDV-gurus to you. ;-)

The 512m is 512 MB of heap for the Java Virtual Machine (JVM).
When it hits that, you'll get the OutOfMemoryError.  For a 2 GB
machine, you could boost it to -Xmx1536m if you want and
see where that gets you.  You'll want to leave some for the
operating system.  Swapping isn't pretty.
