    OOM error  :: EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap

      Hello All,

       

      We are using jboss AS 5.1.0 and we are getting OOM error.The analysis of the heap dump shows folloiwng:

       

      org.jboss.mx.server.MBeanServerImpl
      org.jboss.mx.server.registry.BasicMBeanRegistry
      EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap
      EDU.oswego.cs.dl.util.concurrent.ConcurrentReaderHashMap$Entry[256]


      org.jboss.mx.server.MBeanServerImpl
      mbeanServer of org.jboss.remoting.transport.bisocket.BisocketServerInvoker
      this$0 of org.jboss.remoting.transport.bisocket.BisocketServerInvoker$SecondaryServerSocketThread [Stack Local, Thread]  "secondaryServerSocketThread[0]"

       

       

      20% of the total memory is consumed by ConcurrentReaderHashMap in the BasicMBeanRegistry class.

       

      As this is Jboss code I do not have clue as to why this is happening.

       

       

      Thanks,

       

      Nikhil.
