> {code}
> It looks like a race condition.
> Steps to reproduce:
> 1. Start server A.
> 2. Start client.
> 3. Start server B.
> 4. Stop server A.
> If add Thread.sleep(10000) between (3) and (4) then the client node won't be
> disconnected from the cluster.
> Reproducer is attached [^ClientDisconnectedTest.java].
