In Java Visual VM, I do see the memory grow over time, as the app is used (without a tomcat restart or re-deploy of app and then restart tomcat), but I still have not seen OOME...'yet'. I should leave the server up and running without restarting tomcat, but when I need to deploy new software changes, i can't wait to deploy. :) My apologies, not trying to hijack the thread. just sharing my response to your comments.
