Brandon Williams commented on CASSANDRA-8113:
---------------------------------------------
Also there's no real contract for how often you can update your gossip state if
you want to, so we could have an accidental loop blow the version up and then
run into further problems because now it's being ignored.
> Gossip should ignore generation numbers too far in the future

> If a node sends corrupted gossip, it could set the generation numbers for
> other nodes to arbitrarily large values. This is dangerous since one bad node
> (e.g. with bad memory) could in theory bring down the cluster. Nodes should
> refuse to accept generation numbers that are too far in the future.
