> -------------------------------------------------------------------------------
>
> Key: KARAF-2343
> URL: https://issues.apache.org/jira/browse/KARAF-2343
> Project: Karaf
> Issue Type: Bug
> Components: cellar-features
> Affects Versions: cellar-2.3.0
> Environment: Windows 7, Karaf 2.3.1, Cellar 2.3.0
> Reporter: Ryan Moquin
> Assignee: Jean-Baptiste Onofré
> Priority: Blocker
> Fix For: cellar-3.0.0, cellar-2.3.1
>
> 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:
