Subject [jira] [Commented] (KARAF-5187) Feature install runs 30 minutes and gets out of memory error in Felix resolver code
Date Mon, 12 Jun 2017 15:50:00 GMT

    [ https://issues.apache.org/jira/browse/KARAF-5187?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16046706#comment-16046706

Jay Holloway commented on KARAF-5187:

I am not allowed to share our code; it is proprietary.  Our feature file has been working
with few problems for over a year with Karaf 4.0.4 and 4.0.9.  Recently, we added a lot of
bundles (including wrapped jars) that seems to have stressed the resolver.  Can you tell us
if Karaf 4.1.1 addressed critical resolver issues.  We notice the following within the 4.1.1

     * [KARAF-4701] - Problem installing feature
     * [KARAF-4967] - Upgrade to Felix Resolver 1.12.0

We have tested with Karaf 4.1.1 and know that it processes our feature file with no problem. 
However, upgrades go through a separate architecture team.  We are looking for some type
of confirmation from you in order to convince the architecture team that we need to officially
upgrade to Karaf 4.1.1.

>            Reporter: Jay Holloway
> We are currently using Karaf 4.0.9.  We have a feature file that has worked for us for
over a year.  We have noticed a slight degradation during the feature install in the past
few months as we have added bundles and sub-features to our feature file.  Recently, we added
numerous new sub-features and bundles to our one feature file.  Currently, the feature install
hangs between 15 and 45 minutes until we get a Java heap space out of memory error.  The print
stack trace shows that it is in the Felix resolver the entire time.  However, when we downloaded,
setup and configured Karaf 4.1.1, the same feature file installed with no problem and very
quickly.  Is there something we can do within Karaf 4.0.9 to make it process our feature file
more efficiently without hanging?  Officially upgrading to Karaf 4.1.1 is out of our control.
