Marcus Eriksson commented on CASSANDRA-7262:
--------------------------------------------
I'm a bit worried about callers expecting the session to be actually closed
after calling closeSession, with this it might not be (though, I looked and
couldn't really find a case where they do). Making closeSession synchronized as
well would fix that, wdyt?

> followed by a few more (the reference counter got down to -3). Got the same
> kind of assertion failure on one other node (in a different data centre;
> there are 21 nodes altogether distributed over 4 data centres).
> I've attached the relevant part of the log. It starts quite a bit before the
> assertion failure at the first exception on this node ("Cannot proceed on
> repair because a neighbor ... is dead"), and finishes a few hours afterwards
> when the node was restarted.
> Edit: The following Reference counter assertion failures followed the 1st on
> a different file and have a different stack trace:
