I've just noticed a weird scenario in my UAT environment.
I've got a 3 node cluster but I noticed this morning that nodes 2 and 3 think node 1 is dead. Node 1 however thinks everyone is alive.
In the logs for 2 and 3 it says the following:
WARN [MessagingService-Outgoing-/10.0.8.172] 2015-12-06 02:20:02,987 OutboundTcpConnection.java:423 - Seed gossip version is -2147483648; will not connect with that version
Also it appears node 1 is no longer listening on 9042. It is still listening on 7000 though.
worth noting I'm on Windows Server 2008 R2 and running Cassandra 2.2
