Description

When running dtests for trunk (4.x) that perform some streaming, sometimes a ByteBuf is not released properly, and we get this error in the logs (causing the dtest to fail):

ERROR [MessagingService-NettyOutbound-Thread-4-2] 2017-09-26 13:42:37,940 Slf4JLogger.java:176 - LEAK: ByteBuf.release() was not called before it's garbage-collected. Enable advanced leak reporting to find out where the leak occurred. To enable advanced leak reporting, specify the JVM option '-Dio.netty.leakDetection.level=advanced' or call ResourceLeakDetector.setLevel() See http://netty.io/wiki/reference-counted-objects.html for more information.
