Sylvain Lebresne updated CASSANDRA-15846:
-----------------------------------------
Resolution: Not A Problem
Status: Resolved (was: Triage Needed)
I'll close because as said above, I really don't think this is any indication
of a server bug or issue. But if you have more information that suggests
otherwise, please feel free to re-open with that additional information.
