----------------------------------
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:
