Ok, the other thing that come to my mind is to check the max.poll.interval.ms configuration. You said that "poll is invoked regularly" but this isn't very specific. The default value for max.poll.interval.ms is 5 minutes (300000 millis) so if you are executing a poll regularly each 6 minutes, you will see rebalacing.
