Hello all, I hate to do this, but I've been running a soak test of Kafka Streams on 2.4 and uncovered a number of small bugs that lead to Streams losing threads until there are none left. This condition only arises when using EOS in a highly flaky networking environment.
I've included a lot of details in KAFKA-9231, in particular my last comment: https://issues.apache.org/jira/browse/KAFKA-9231?focusedCommentId=16985429&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16985429 Please take a look and see if you agree whether it warrants cutting a new RC early next week once the fix is merged.
