ColdFusion memory issues

Question

Our production server has 2G of memory installed, however we
can't allocate more than about 1280m to the ColdFusion process.
Here is our java.args value:
java.args=-server -DJINTEGRA_NATIVE_MODE
-DJINTEGRA_PREFETCH_ENUMS -XX:+ForceTimeHighResolution -Xmx1280m
-XX:MaxPermSize=128m -Dsun.io.useCanonCaches=false
-Dcoldfusion.rootDir={application.home}/../
-Dcoldfusion.libPath={application.home}/../lib
-XX:+UseConcMarkSweepGC -XX:+UseParNewGC
-Dcoldfusion.classPath={application.home}/../../classes,{application.home}/../lib/updates ,{application.home}/../lib/,{application.home}/../gateway/lib/,{application.home}/../wwwro ot/WEB-INF/cfform/jars,D:\\inetpub\\wwwroot\\CustomTags\\common\\CFX
Whenever I try to bump up the Xmx value, the service won't
start. Is there a limit as to what we can allocate to the JVM?
Environment:
Win2K
CF7 fully patched
JVM 1.4.2_15
Thanks for any help you can offer.

Yes, the limit is the 32bit windows operating system. To make
use of
more one needs to use 64bit operating systems. There are many
blogs and
other information I have read the spells out the specifics on
gory detail.
