      • Call the script bin/jboss-cli.sh with the command :read-children-names(child-type=host) time and time again, example:
        while true; do jboss-cli.sh --connect --user="myuser" --password="mypassword" --command=":read-children-names(child-type=host)" && sleep 2; done
      • Monitor the jvm and see lots of space taken in eden, propagated to old gen by gc and never getting collected from there

      Use -Djboss.remoting.pooled-buffers=false on the command line to disable the byte buffer pooling.

      Calling the cli using the command:
      jboss-cli.sh --connect --user="myuser" --password="mypassword" --command=":read-children-names(child-type=host)"
      leaks memory to old gen. Eventually the host controller goes OOM if called to often.
