   From the logs, I see the following last assignment:

   } with followup probing rebalance. (org.apache.kafka.streams.processor.internals.assignment.HighAvailabilityTaskAssignor)
   ```
   `5c2faa18-0876-498a-b00d-9b5bd62297d1` is the Streams client that is shutdown uncleanly and verified when it restarts. The verification whether `5c2faa18-0876-498a-b00d-9b5bd62297d1` processed records will never be satisfied since the Streams client only has standby tasks.
