I've found the cause of sudden termination.
The method akka.remote.EndpointManager#createEndpoint contains an assertion:
assert(writing || refuseUid.isEmpty)
If an endpoint which was previously quarantined reconnects, refuseUid is
existing.
As the remote endpoint sends a message it a reading endpoint must be
created - writing is false.
The resulting AssertionError smashes through all supervising parents until
the ActorSystem terminates.
This is the stacktrace right before the AssertionError is thrown:
"Node-A-akka.remote.default-remote-dispatcher-6@1930" prio=5 tid=0x10

It seems to be a bug, shall I file a ticket?
