I have been doing some more research and I am beginning to think this post describes the cause of the issue
http://stackoverflow.com/questions/3320400/to-prevent-a-memory-leak-the-jdbc-driver-has-been-forcibly-unregistered Has anyone deployed and application to production with either Tomcat 6 or 7 with these messages? If so, did they have any issues? We are using out of the box EOF, the article talks about the need for connection pooling. I have read the Cayenne supports connection pooling. Does EOF? Or maybe we switch to monitor for deployment on RHEL6. I read the articles and considering it. Anyone done this?
