JVM 32bits Xmx limitation

Hi All,

I have an old java application running on old 32bits windows 2000 server, 2G
Ram with JDK5. Originally I can startup my apps with -Xmx1412M. It's work
for a year. One day, I restart windows but fail to start my app. It said
'Could not reserve enough space for object heap'. I have to decrease the Xmx
to 1200M to make it work. Please advise.

The server reboots everyday. No windows updates (and no software newly
installed) for 3 months.

I increase the physical memory to 4GB, it didn't help.

Any workaround?

Regards,
Ken
