> Messages get passed to {{NonBlockingConnection}} in the {{send()}} method which holds them in the private {{_buffers}} field. The {{doWrite()}} method consumes the messages and disposes them from the IOThread. However, there is no limit on how many messages/buffer can be in the {{_buffers}} variable.
> In one test there were about 2000 {{QpidByteBuffers}} in {{_buffers}} accounting for approximately 500 MBytes direct memory.
> This happens can cause the Broker to go OutOfMemory especially when the client is useing prefetch.
