             Summary: Installing Cellar 2.3.0 cellar-event crashes Karaf 2.3.1 after a few seconds...
                 Key: KARAF-2343
                 URL: https://issues.apache.org/jira/browse/KARAF-2343
             Project: Karaf
          Issue Type: Bug
          Components: cellar-features
         Environment: Windows 7, Karaf 2.3.1, Cellar 2.3.0
            Reporter: Ryan Moquin
            Priority: Blocker
         Attachments: karaf-2.3.1_cellar-2.3.0-memory_problem.JPG

After I installed cellar-event (it seems like it should be installed), my cpu usage went to 100% the memory usage rapidly increased to 400MB+, invoking a garbage collection manually only brought it down to ~398MB. After a minute or so Karaf ran out of memory.  I'm attaching a screenshot where you can see the point in cpu usage when I installed cellar-event, and it looks like after maybe 2 seconds it takes a nosedive. The cellar multicast thread must have some sort of memory leak  I can see if I can get any more details.  Below is the stacktrack in the console when Karaf finally had enough:
