Did you experiment this error with your test?

You can configure this, this occurs when the client is not reading quickly. It frees the writing thread and allows it to return to the servicing thread pool, allowing a sub-system to continue delivering the payload in the background. See the following to configure.

public TransportSocketProcessor(TransportProcessor processor, int threads, int buffer, int threshold) throws IOException { this(processor, threads, buffer, threshold, false); }

Here threshold represents the maximum size of the output buffer. You can reduce it to something like 1K which should resolve your memory issues.
