Hello.

I got a question regarding memory usage on a deployed system.

VirtualMachine, win2008 x64, 4 cpu, 6gb Memory, Java x86, Geoserver 2.5.1
running inside Tomcat7.
using the following relevant options.
set JAVA_OPTS=%JAVA_OPTS% -server
set JAVA_OPTS=%JAVA_OPTS% -Xms1024m -Xmx1024m -XX:MaxPermSize=256m
-XX:PermSize=128m
set JAVA_OPTS=%JAVA_OPTS% -XX:+UseConcMarkSweepGC -XX:+UseParNewGC
-XX:ParallelGCThreads=4 -XX:NewRatio=2 -XX:+AggressiveOpts

All is fine but, the memory usage on the machine is as follows:
Physical Memory:
Total: 6143
Cached: 3296
Avaliable: 3398
Free:50

My question is regarding the ammount of avaliable memory VS the free.
Why is this happening? is it because of the limit on the x86 java VM ?

if someone can clarify, it will be most helpfull.

Regards,
Filipe
