    • Type: Bug
    • Status: Closed
    • Priority: Major
    • Resolution: Done
    • Affects Version/s: jboss-fuse-6.2.1, jboss-fuse-6.3
    • Fix Version/s: jboss-fuse-6.2-patches, jboss-fuse-6.3
    • Component/s: Fabric8 v1, Karaf
    • Labels:
      None
    • Environment:

      JBoss Fuse 6.2.1 Karaf / Fabric - Reported on Rollup 1 / 090, confirmed on Rollup 2 / 107

    • Steps to Reproduce:
      Hide

      1. Deploy JBoss Fuse 6.2.1 / Karaf (I used Rollup 2 for testing)
      2. Create a Fabric with fabric:create --wait-for-provisioning
      3. Create a child container
      4. Attach a profiler like JVisualVm to the child container process
      5. Alternately provision and remove the JBoss Fuse Full profile on the container.
      6. Watch the PermGen usage climb in stair-steps until an OOM is thrown

      Note: I did see one stop the world GC in which the PermGen dropped considerably, but following that event was able to force the OOM by continuing to redeploy.

      Description

      After repeated redeployments of a profile to a Fuse Fabric container, PermGen space is slowly consumed until PermGen is maxed out and an OutOfMemory:PermGen error is thrown and the container becomes unresponsive.

      Some space seems to be recovered after each redeployment, but the amound recovered gets progressively smaller until the OOM is thrown.
