Subject [jira] [Commented] (KARAF-2340) Stock Karaf 2.3.1, Cellar 2.3.0, hanging on installing eventadmin
Date Sat, 25 May 2013 14:42:20 GMT

    [ https://issues.apache.org/jira/browse/KARAF-2340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13667089#comment-13667089
] 

Ryan Moquin commented on KARAF-2340:
------------------------------------

I installed the eventadmin feature since I already knew that an NPE would occur if I tried
to install cellar-event without eventadmin.  This is the first and only time I've ever seen
that happen.  I DO have to say, I didn't have synchronous=true set for blueprint when eventadmin
hung.  So this may just be a result of that.  After I remembered that wouldn't have been set
in Karaf-2.3.1 and set it, I had no problems with any features hanging when I installed them.
 So those feature installation hanging issues may be just invalid issues that are my fault
and only need to figure out the CPU and memory usage issues.  If you think the hanging was
only because of synchronous=true not being set, then maybe we should rename this bug to reflect
the CPU usage issue.  I realize I mistakenly ended up making this bug about two issues (I
guess because the first problem didn't happen against when I set synchronous=true).

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.
