I'm going to have to clarify a few things, here. First, you say that the user can use the web app without any problems. Then you say that as soon as the web application starts, it becomes unresponsive. So, which is it: does the web application "run happily" or does is it unresponsive from the outset? Then, after the user logs-out (from the either completely responsive or completely non-responsive web application), the web application becomes (or remains) unresponsive? > If we run tomcat in non-SSL mode, there is no problem.
