Here is the setting that I am starting up the JBoss server with
Code:
JBoss JAVA_OPTS="-server -Xms512m -Xmx1024m -Dcom.sun.management.jmxremote -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=4142,suspend=n -Dprogram.name=$PROGNAME"


Changing the Xmx size from 512 to 1024m had no change on where I got the permGen error. Using the jconsole I was able to see that JBoss was able to get around 67 Meg before getting the error.

What settings can I change to get around my problem?

Thank you,
David

That did the trick except for when I redeploy the system. When I redeploy the Perm memory is not getting released or recycled.

Instead it just grows.

Does the SessionFactory need to be closed or release when the ejbRemove() method is called? A reference to SessionFactoryis opened using JDNI inside my stateful session bean.

Thank you,
David

Register context listener to close factory, probably it will help, but it can take time to find right locations for jars to avoid classloader leak.

I am sorry. I did not follow that. How do you register a listener on the context?

I looked at the context methods and at the session factory's methods but I don't see any methods that are to be used to add a listener.

Is there a Wiki for this or is this in the Hibernate API doc?

Thank you again,
David

It is from servlets API.
