It could be that Tomcat is attempting to resolve the SYSTEM URL for
certain XML files it uses to configure itself. Could you re-enable the
DROP and take a thread dump during the long wait? That will help
nail-down the problem. Perhaps Tomcat can be modified so that it does
not perform this look-up.
