Description

If MessageWorker thread fails by some reason (i.e. because of uncaught exception) it will move a node to "zombie" state. The node will still accept messages through SocketReader but won't process them.

At some point of time the node will fail because the message queue will be overflowed.

Such a node must be stopped as soon as MessageWorker terminates.
