that is really strange. where could be the difference? do you use the full profile? may i see your standalone.xml?

thank you for your support.

i finally found the difference. your standalone was same as mine.  but i think your  system is not on a windows machine...

i tried to run my test under ubuntu and everthing works fine, but when i run it on my windows box at work the OutOfMemory occurs.

so now i will try to manually clear the array of nettys BigEndianHeapChannelBuffer

wasn't that easy to clear this buffer...

what i finally did is the following code if onMessage does nothing

if ( message instanceof HornetQMessage ) {
    try {
     HornetQMessage hm = (HornetQMessage) message;
     if ( hm.getCoreMessage().isLargeMessage()) {
      ClientLargeMessageImpl  lm = (ClientLargeMessageImpl ) hm.getCoreMessage();
      DynamicChannelBuffer cb =   (DynamicChannelBuffer) lm.getBodyBuffer().channelBuffer();

      Field buffer = cb.getClass().getDeclaredField("buffer");
      buffer.setAccessible(true);
      buffer.set(cb, null);

do you see any problems?
