    EAP 6.2.0 redeploy causes CPU & GC activity

    davidforce Newbie

      Hello, I've got an issue regardin 6.2.0 on windows 64bit. Vanilla standalone, hardly any changes in standalone.xml or similar.

      When I deploy a .ear (7,6 mb) more than 1 time something goes bad.

      I see CPU increase in task manager.


      When I inspect with VisualVM I see increased GC and CPU usage after second deploy.

      I can repeat it over and over again.

      I undeploy first - same issue.

      I deploy diffrent methods, gui-upload, autodeploy-folder, maven - same issue.

      I undeploy - problem persists!?


      I can NOT repeat this behaviour on EAP 6.1.1, see second image.


      INFO: Do use jboss-deployment-structure.xml to exclude loggers. Application has lots of @Stateless, some @Schedule, JSF, Oracle DB etc. But only pure JEE6 stuff.

      Looking at changes 6.1 --> 6.2 I see alot regarding deployment... but this seems crazy.


      I've started looking at https://bugzilla.redhat.com/buglist.cgi?bug_status=__open__&content=deploy&no_redirect=1&order=changeddate%20DESC%2C&product=JBoss%20Enterprise%20Application%20Platform%206&query_based_on=&query_format=specific and see some open regarding deployments.


      Below, CPU and GC go crazy at second deploy.



      Below 6.1.1. CPU spikes at deploys - fine.

      (sub-question, is it norman for total loaded classes to increase at each deploy?)
