Java HotSpot Virtual Machine

Hi,

I an working with J2SE 1.4.2 (exactly 1.4.2_08) on Windows 2003 Server SP1
The server i use have 4Go of RAM..

As Windows 2003 is a 32bits OS, the limit memory size for jvm is supporsed
to be 2048 Mo. Am I right?

When i try to set -Xmx parameter to 2048m, i receive the following message:
"Error occurred during initialization of VM
Could not reserve enough space for object heap"

If i try reducing this parameter to -Xmx1536m, it did not work too. The
first value to make it work was -Xmx1408m.

How can I do to make it work allowing 2040Mo to the jvm?

Regards,

Yannick
