We've been using parallel deployment for some time now with tomcat 7.0.25. For the most part the parallel deployment is a really nice idea, particularly because we don't have sessions serialised and clustered across all running instances.
However, we've had mysterious problems for some time now where fixes we've applied to the application don't seem to work. We added some logging and have confirmed that some requests are still being served by the OLD instances of the application which are still deployed in the tomcat container but have an older version and therefore should not be responding. We might have two apps like this (using a format of YYMMDD and a two digit sequence): enrol##12022203.war enrol##12021503.war We would expect that requests would be served from only the newer application, but we find that requests continue to be served from the old, even though all the sessions to the old application are long dead. Just to confirm things we have another application which does not use sessions at all. It also has the same problem: requests are being served by the wrong application. In Tomcat Manager, the old application is still marked as running, but we thought this is just how it appears in the UI. Clearly there is something not right here. 1. Is this a known issue? 2. Is there some way to get the old application to fully undeploy as soon as it has no live sessions? We have been thinking about writing an external application to poll using JMX and do this, but that's quite a bit of work. It would be nicer if this happened inside tomcat itself. 3. Is there some resource we might be hanging onto which is preventing the old application from properly stopping? 4. Should the tomcat manager show the older apps as still running or should they be shown as stopped?
