Jacques Le Roux updated OFBIZ-4043:
-----------------------------------
Description:
# 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$Entry[]", loaded by "<system class loader>"
Keywords
java.net.URLClassLoader @ 0x7f3681c111f0
org.apache.derby.impl.jdbc.EmbedConnection40
java.util.WeakHashMap$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
