Sophie Blee-Goldman commented on KAFKA-8948:
--------------------------------------------
Turns out this was most likely a real issue that just happened to disappear
again for some reason – a bug in this system test was discovered to be causing
failures after subsequent runs on the same machine since it did not properly
clean up after the test. That bug (and most likely also this ticket) should be
fixed by [https://github.com/apache/kafka/pull/7693]
> Flaky Test StreamsEosTest#test_rebalance_complex is broken for multiple runs
