Increasing JVM heap beyond 1.3GB in Win2K

[Barry Hawkins <ly5t5@allthingscomputed.com>]

List,
	Has anyone successfully managed to get a JVM heap size on Windows 2000 
using the Sun 1.4.2 JVM?  Our team has a web app in ColdFusion MX 
(CFMX) (long story, stay with me on the JVM thing) which runs on an OEM 
version of Macromedia JRun 4.  JRun uses the 1.4.2 JDK on Windows 2000, 
and Macromedia recommends setting the JVM to have a minimum and maximum 
JVM heap size of 1024MB.  They also recommend tweaking the JVM settings 
if you need to.  However, they offer very little advice on doing that, 
and the advice they do give contains broken links to J2ME resources.
	The JVM heap size for our app is nailed at an average of 1,473,910,395 
bytes or ~1.36GB.  Stuff I have found with Google and on the Apple Java 
mailing list indicate that the Sun JVM on Win2K will only get to about 
1.3 - 1.6GB.  Has anyone been able to successfully get a heap size 
larger than that on Win2K?
	Along those lines, what JVMs are folks using on their production 
servers in general?  Which JVMs tend to get along with which app 
servers?  I'd love to hear your input.

Thanks,
