[jira] [Commented] (KARAF-2340) Stock Karaf 2.3.1, Cellar 2.3.0,
hanging on installing eventadmin
[ https://issues.apache.org/jira/browse/KARAF-2340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13667079#comment-13667079 ]
Ryan Moquin commented on KARAF-2340:
------------------------------------
Just wanted to mention that I had forgotten to add the synchronous=true for blueprint when I ran Karaf 2.3.1. I'm not sure if that made a difference, but just to cover my bases. I tried again this morning just adding the cellar url, I installed the Karaf Webconsole, installed Cellar and then installed the cellar-webconsole. All of those installed quickly as I would expect. If I look at the log, there isn't any activity with INFO level other than what I would normally expect to see with Cellar starting up. My CPU though is at a constant 20% usage and there is a lot of garbage being created. There doesn't appear to be a memory leak, just a lot of garbage. I'm attaching a jvisualvm profile snapshot I took after letting it collect results for a few minutes and you'll see that hazelcast is generating a lot of activity. I'm pretty sure all the views are part of the generated profile (decided to be smart this time and create the profile instead of a screenshot)
Is this something that is normal with Cellar? Does something need tuned? Is this an issue with Hazelcast? Or is there something in Cellar that's being a little too aggressive regarding looking for cluster members and the such?

> I've been working on a demo for several weeks to promote Karaf and Cellar. Even thought Karaf 3.0.0 seems to work great, the addition of Cellar just isn't ready yet. When I tried Karaf 2.3.2-SNASHOT with Cellar 2.3.0, my CPU went to 25% and hazelcase 5 seemed to be going a bit crazy. So I moved to Karaf 2.3.1 and Celler 2.3.0. I was able to install cellar but when I finally typed the correct comment to install the admin, my cpu utilization went to 25% and the features:install command never returned.
> Attached are some screenshots of sampling from jvisualvm (the profiler seems to through karaf into fits). I'm a little lost on how to get Karad and Cellar running correctly together.
