get the outOfMemory error message.
Java is designed so that it can not consume all of the resources on a
machine, so it has it's own memory limits. By default the memory limit for
a 1.4 java application is 64Mb. So even if you have 4Gb of RAM PCGen will
only use 64Mb by default.

256M of memory. In general you would not want to set this value to any
more than about 75% of your real memory size (garbage collected languages
like java do not know about which of your memory is real and which is
virtual so the garbage collector slows right down if it has to swap items
in first in order to check if they are still used ;O)
I tend to run most java apps with "-Xmx384M" but that is because I have a
development machine with a lot of memory.
