> # Using [Mat|http://www.eclipse.org/mat/] on a stable heap dump
> I generated these report
> 110 542 instances of "org.apache.derby.impl.jdbc.EmbedConnection40", loaded by "java.net.URLClassLoader @ 0x7f3681c111f0" occupy 415 680 440 (79,89%) bytes. These instances are referenced from one instance of "java.util.WeakHashMap$Entry[]", loaded by "<system class loader>"

> org.apache.derby.impl.jdbc.EmbedConnection40
> java.util.WeakHashMap$Entry[]
> It's not quite clear to me how this happends, but I'm quite sure it happens in stable demo and maybe also in trunk. I have also attached a screen-copy with more information
> # Using jstack on trunk I found that org.ofbiz.content.cms.CmsEvents.cms(CmsEvents.java:289) seems a deadlock culprit
