[jboss-user] JBoss memory leak?

Hello, everybody. I have a problem with JBoss leaking memory over repeated re-deployments of same ear file. Obviously the ear file changes slightly between the re-deploys, but name is the same, so it should replace the old one entirely on each re-reploy. Over time, after dozen or so hot-re-deploys, JBoss stops to OutOfMemoryError at deploy time. To trace the issue I captured full memory dump and analyzed it with Ecliple Memory Analysis Tool. Here is a screenshot from the data it shows: <http://zds.iki.fi/zds/temp/jboss_leak_0.png> And the main leak point as text: One instance of "org.jboss.mx.server.MBeanServerImpl" loaded by "org.jboss.classloader.spi.base.BaseClassLoader @ 0x7ffe9d4baa50" occupies 83 098 176 (21,06%) bytes. The memory is accumulated in one instance of "EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap$Entry[]" loaded by "org.jboss.bootstrap.NoAnnotationURLClassLoader @ 0x7ffe9c604bb8".Keywords org.jboss.bootstrap.NoAnnotationURLClassLoader @ 0x7ffe9c604bb8 org.jboss.classloader.spi.base.BaseClassLoader @ 0x7ffe9d4baa50 org.jboss.mx.server.MBeanServerImpl EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap$Entry[] Looking further down the object tree, I get drown to sea of interlinked HashMaps. It would seem the memory leak, if it exists, is about having lots and lots of internal bookkeeping information gathered in small pieces to interlinked network of object references. So, the question is, what can I do to this? -Jari
