While evaluating Resin 4.0.16 we are seeing something that makes me really concerned. It appears as if after a redeploy there can be two instances of our main app running.
I was made aware of this by noticing that timed servlets (<run-at ... />) were having concurrency issues and logging the same event twice within the same second. This made me add some extra logging in a <load-on-startup/> servlet, and I can actually see that at some reploys, the same web app is initialized twice - in different, concurrent threads and different classloaders. For example one instance may be initialized by Thread[http://*:8080-776,5,main] and at the same time (give or take a few seconds) another one by Thread[resin-366,5,main]. I cannot deliberately recreate it by simply redeploying (which makes it less likely to be a configuration issue). But it happens about daily on our test server; possibly issuing requests on a session in the app while redeploying is a factor. We are not using versioning. dependency-check-interval is set to 20 seconds. The "extra" app does not appear in the admin console. How can we figure out what is going on here??? -- </Mattias> _______________________________________________ resin-interest mailing list resin-interest@caucho.com http://maillist.caucho.com/mailman/listinfo/resin-interest
