The code you posted should not leak channels, so something else must be
going wrong. Are you certain that the "channel.close();" line is being
executed? Is it possible that a different client is connecting and
failing to properly close channels?

If you are still stuck after checking this then you may want to consider
connecting to the broker via a protocol tracer which will confirm
whether your client is closing the channel or not:
