Matthias J. Sax commented on KAFKA-17098:
-----------------------------------------
[~cadonna] – do you think you recent fix for state updated (ie from today)
addresses this issues:
[https://github.com/apache/kafka/commit/25230b538841a5e7256b1b51725361dd59435901]
We did discuss internally about potential lock issues, which you did rule out
for the error we say in our own soak, but maybe this one is different? But I
would assume you might need logs (\cc [~eduwerc] do you happen to have logs?)
to judge?
