David Jacot commented on KAFKA-13592:
-------------------------------------
[~Kvicii] I don't know the reason of this issue... However, I am pretty sure
that it is an issue similar to https://github.com/apache/kafka/pull/11666. I
have noticed that the test fails from times to times in our CI. I guess that
you could reproduce it by running the test in a while loop in bash.
