The first thing that come to my mind is: are you using the 32 bit java
on your 64 bit computer. If so you shouldn't have any problems. If not
then try to increase the heap as David proposed . Also this can be
done by setting the environment variable  ANT_OPTS environment
variable.

P.S.What is the available RAM memory on both of your computers? Is
there any difference?
