IIRC, the above unLock call is just a tool to speedup the shutdown process. Even if it fails, it is not a big concern. > I am using Tomcat 6.0.14. > Any suggestions? Plan for upgrade, to 6.0.26 or to 6.0.27 when it comes out. 6.0.14 is several years old and IIRC there were some changes to the shutdown process, that might affect the above issue. > I forgot to mention java 1.6.0_18 > Windows Server 2003 Thank you for following up to provide the above details. It is appreciated. The unlock call establishes a connection to the port where connector listens for the incoming connections. That will unlock the thread that waits for them on the socket, allowing it to shutdown immediately. It would be a concern if external connections to Tomcat fail. (But if they do, it would be one of the reasons to restart Tomcat).
