-------------------------------------------------------------
[~bchen225242] No it isn't happening all the time. Interestingly, I have two
different instances of the same 2.3.0 client code running against the same
2.3.0 Kafka broker. The only difference between them is the configured name of
the group, and the topics being consumed. One of them get this error, the other
does not.
