> 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.
