> CASSANDRA-8336 introduced a race condition causing gossip messages to be sent
> to shutdown nodes even if they have been already marked dead.
> That's because CASSANDRA-8336 changed (among other things) the way the
> SHUTDOWN gossip message is sent by moving it before the gossip task (the one
> sending SYN messages), and by putting a few secs wait between the two; this
> opens a race window by the receiving side between the time the SHUTDOWN
> message is received, causing the outbound sockets to be closed, and the
> moment the other side listening socket is actually closed, meaning that any
> SYN gossip message exchanged in such window will reopen the sockets and never
> close them again, as the node is already marked dead.
