I just hit the same thing. This is Suse 10.1 on a machine with 2gb of RAM. I had dynamically reloaded my application about two dozen times. Would that make a difference? It does worry me to see that when I think that I'll be deploying this as a live application serving millions of hits at some point. It's one thing to run into it in development, but in production, that is a killer. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3965172#...
