I just grabbed the pop3 beans from: http://www.alphaWorks.ibm.com/Home/ I unzipped the file, ran the demo, and started getting a bunch of bogus free messages. Then I quit the application and the jvm dumped core. It's extremely reproduceable. I'm running Redhat 5.1 with all of the latest updates and the 1.1.6v2 jdk. Thanks for a great port, Steve. david
