    ColdFusion memory issues

    hans blix
      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.
