Another Out of Heap Space Thread

I am trying to analyze about 400,000 records w/ 5 attributes on Decision Tree learner.  I end up running out of heap space.  I am currently using the xms/xmx2048m option.  My system has 4 GB of memory, but running on a 10 year old hard drive so it really slows down if I have to use the swap space (Running Ubuntu Linux 10.04).  Aside from upgrading my RAM and killing some processes to free up 3 GB for the heap, is there anything else that I can do besides upgrading my system memory?  Is there a way to make the operator conserve memory?

    Hi there,

    It would help to see the code, it nearly always does  ;D

    Hi,
    another valuable information would be, when does the process exit? During loading the data or while learning the tree?
