Brandon Williams commented on CASSANDRA-8224:
---------------------------------------------
This is a prime example of why you should have ECC memory, so we don't have to
exert ourselves in software to accomplish what hardware can already provide.
That said, the way I see this working is to provide the checksum as a gossip
state itself (that way older nodes can just ignore it) which is a checksum of
everything except the checksum state itself. But again, it does feel like a
problem better solved elsewhere.

> We have seen that a single machine with bad memory can corrupt the gossip of
> other nodes and cause entire cluster to be affected. If we store and pass the
> checksum of the entire state, we can detect corruption. If a bad machine
> tries to bump the generation number or other things, it will be detected and
> ignored.
