Brandon Williams commented on CASSANDRA-17922:
----------------------------------------------

I suggest we simply [add some retries|https://github.com/driftx/cassandra-dtest/tree/CASSANDRA-17922] which should [be safe|https://ci-cassandra.apache.org/job/Cassandra-devbranch/1972/] in any case.

> In CASSANDRA-17872 we added protection around failures similar to this, caused by the port being in use, which is no longer the case:
