[infinispan-issues] [JBoss JIRA] Commented: (ISPN-868) Running out of memory using Infinispan after adding a small number of entities

    [ https://issues.jboss.org/browse/ISPN-868?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12575110#comment-12575110 ] 

Tom Waterhouse commented on ISPN-868:
-------------------------------------

A new test project has been attached that will function correctly.  Infinispan and JBossJTA both include jboss-logging but different versions.  That has been fixed.

The updated proejct includes the configuration from option #3 below.  I ran the test FillCartonTest.testKiwisAllInOneCarton() with the VM argument -Xmx256m.  The test made it to somewhere between 3400 and 3500 Kiwi objects added to the Container object before generating the message 'java.lang.OutOfMemoryError: GC overhead limit exceeded'.

> While running a load test data builder for our application we ran out of memory very quickly.  A simple test case (attached) was created to duplicate the issue.  We found running the simple test case illustrates that Infinispan uses a large amount of heap space.
> As a reference the same test was run using EHCache 2.2.  Memory usage was much lower; we never ran out of heap space.  Note that EHCache was used as a reference only, our goal is to go to production with Infinispan.
