Yes, that's what it should look like.
Starting with Java 5 (1.5), anything that has more than 2 physical
processors or 2 GB of RAM is declared a server-class machine, and will
use the -Server option for the JIT compiler. If this is detected it
sets the min heap size to 1/64 available RAM up to 1GB and max of 1/4
available RAM up to 1GB.
Using the -client option uses a different JIT compiler resulting in a
smaller memory footprint and quicker operation of some applications that
don't need the advanced support of the server comiloer (i.e. at the end
of the day it loads less code).

Craig,
thanks for your reply. This is my current line:
/usr/java/bin/java -jar /root/bin/dst/kiosk.jar
So is this what it should look like?:
/usr/java/bin/java -client -Xms16m -Xmx32m -jar /root/bin/dst/kiosk.jar
I up'd the ram amount to be safe.

You can also control the initial heap and max heap size with the
-Xms<size> and -Xmx<size> arguments
For example if you wanted to set an initial of 8MB and a Max of 16MB
you'd do
java -Xms8m -Xmx16m YourJava.app

Can you try adding -client argument to your java argument?

Looking to see if anyone else has seen this. Running SRSS 4.2
latest patches installed on Solaris 10x86. I have a simple java gui
for our kiosk sessions. See attached pic. It was developed using
NetBeans 6.8. The entire Java jar file with libs is 156Kb in size.
But when I looking at the kiosk sessions this little java app is
chewing up 571MB of memory!

Is this typical of Java?
