It is running an application inside 4.1.37 with Java 1.4.2. Given that we only have a 32 bit address space, is it fair to say that I can't use more than 2G of RAM for my Java virtual machine? I tried to prove this with: export CATALINA_OPTS="-server -Xms2512m -Xmx2512m" but so far I've not seen memory usage go over 1G. What's the best way to make to most of the RAM?
