Hi Christopher > Which classes, specifically?
Thousands of Session instances inside the sessioins attribute of the org.apache.catalina.session.StandardManager. In theory we are not calling getSessions on the middle tier and as you mentioned, we have no JSPs either. However, we might be passing a jsession parameter from the frontend to the middle tier. Would that be an issue, causing the session to be created in the middle tier? >> What is the impact of using session-timeout = 0? > > Your sessions will never time out, and your problem will likely get worse. In the only place I see any reference to it is here: http://tomcat.apache.org/tomcat-6.0-doc/api/org/apache/catalina/session/StandardSessionFacade.html#setMaxInactiveInterval(int) And it says that "A negative time indicates the session should never timeout.". there is no mention about setting as "0".
