The option "-Xss" is setting the stack size to 5GB. Is
this your intention? Have you tried setting "-Xms" ?

Hi,
I am running an application on system having 32GB RAM
and of 64 bit architecture in Red Hat Enterprise Linux
AS release 3 (Taroon).
The program would build a model from a large input
file "train.arff".
The command I am using as:
java -Xss5g -Xmx5g -verbose:gc -XX:+PrintGCDetails
-XX:+PrintGCTimeStamps
weka.classifiers.functions.MultilayerPerceptron -t
train.arff -d model
The program is running since 8-10 hours and its not
crashing neither it is generating the model. It is
generating the GC output like

If I provide less memory the program ends up with
OutOfMemoryError.
Can anybody suggest me if I am allocating wrong memory
to the application.
