Hi. Are you running a 64bit or 32bit OS? If 32bit the JVM will not be able to assign higher that 2gb for a single process (which includes system overheads etc). You will need to move to a 64bit OS to be able to create higher Heap.
I would check your OS memory/kernel/process memory documentation if I were you. There were recently some posts on this list dealing with Tomcat memory - would suggest reading thrugh those for some useful tips too.

Hi! I'm having trouble getting my Tomcat 5.5. production box to use more than 1.1Gb of memory. 1) When I use the Configure Tomcat console's Java tab to set the Maximum Memory Pool I can only use a max of 1999Mb. If I go above that the Windows Tomcat service will fail to start. 2) Tomcat will start with a configured value of 1999Mb, but when I view max memory in the app it says that it has a max of about 1140Mb (sorry, I forgot the exact value... possibly 1048Mb, but i don't remember it being one of the magic numbers). Is this a JVM issue or a Tomcat issue? I've got 4Gb of ram on the dedicated Tomcat server and I'd like to give 3Gb to Tomcat.
