Has this been solved yet? I'm seeing it with 5.2.0. I'm seeing an issue that occurs on some machines (where machines are identical regarding OS, Java version and hardware).
Consumers that are on the same machine as the producer usually work fine. It's a major blocker for us - any comments highly appreciated.
