java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0)
Java HotSpot(TM) Client VM (build 1.3.0, mixed mode)


We have an application that can use large amounts of memory on a SMP
Intel processor system with 4 processors and 4GB of physical memory
under Solaris for Intel 2.6.

When attempting to create a JVM, even simply to get the -version
information, with a value for the maximum heap size in excess of 2014mb
I get:

>$ java -Xmx2015mb -version
> Error occurred during initialization of VM
> Could not reserve enough space for object heap

Why? There is lots more physical available memory on the machine. (A
simple C program can malloc almost 3500M before failing with a "Not
enough space" error.)

I suspect the response is going to be the JVM can't get the requested
amount of _contiguous_ memory. If so, I suggest that limitation (and
some indication of how one can determine or change that) be added to the
-Xmx documentation. If not, what is the problem?

This, plus the HotSpot Virtual Machine Error, Internal Error bug with
  bug id 4355769 are bringing this work to a stand still.
