StreamThread dies with the following exception:
The reason is that the restore consumer is not subscribed to any topic. This happens when a StreamThread gets assigned standby tasks for sub-topologies with just state stores with disabled logging.

Both StreamThreads should die with the above exception.
The root cause is that standby tasks are created although all state stores of the sub-topology have logging disabled.
