Memory for Java problem with 2.4.20 kernel

How much physical memory do you have?  What is the version of your JDK?
Depending on other applications that are running, you could be limited by
memory (although since you are sizing your heap to a max size of 1.8GB (more
or less) I am assuming you have more than 2GB, or are not running any other

It may serve you better to set your initial size and max size to the same
value, there is less overhead when the JVM does not have resize itself
periodically, but with this case, you need to have a very good idea of the
operational parameters of your app.

Running a 2.4.20 kernel on a Dell 2650, the .config file is attached and 
I am seeing this error if anyone has any ideas I would love to hear them.

Executing cagent loop: java -Xms512m -Xmx1798m 
 eHandler -jar Fast-PartnerSite-1.1-cagent.jar
 Error occurred during initialization of VM
 Could not reserve enough space for object heap

We are able to use 750 instead of 1798, or even 1024
