The current/standard version for Cassandra in production is 3.11.4, which at this point is quite old (February 2019). We've recently tested 3.11.11 on AQS to solve a memory leak (the memory leak was solved), and consensus seemed to be that we could roll it out to the remaining clusters. We've since encountered T309736: Cassandra nodetool not working after openjdk-8 upgrade to 8u332, a fix for which has been included in 3.11.13. The delta between 3.11.11 & 3.11.13 is relatively small, I propose we reset on 3.11.13, first upgrading AQS, and then the remaining clusters.
