Sorry for the delay - election madness.
-d64 must be used on systems with 64bit architecture in order to address
more than 1.5-3.5G of memory (depends on the platform).
>From the manual:
-d32, -d64
Specified whether the program is to be run in a 32-bit or 64-bit
environment if available.
Currently, only the Java HotSpot Server VM supports 64-bit operations and
the -server option is implicit with the use of -d64 . This is subject to
change in a future release.
If neither -d32 nor -d64 is specified, the default is to run in a 32-bit
environment, except for 64-bit only systems. This is subject to change in
a future release.
See

more information.
