I have a cluster of 15 nodes/boxes. I start the nodes roughly at the same
time. One of the nodes is behaving oddly and continually logging "Ignoring
received gossip intended for someone else". However, the node does seem to
work for a while before being being dropped from the cluster. Basically
this one node seems to think it is someone else, whilst also behaviouring
as itself. The code and config is exactly the same on all 15 nodes so I
don't understand why I'm getting this issue on only one node. Maybe this is
a hardware issue?
Some logging:

]
}
remote.netty.tcp.hostname = 172.17.102.128
}
I thought it was weird that the unique address in the gossip messages
referred to a negative number. I added log.info(s"my unique ID:
${AddressUidExtension(actorSystem).addressUid}") to the confused node (I
hope this is the correct code) and it gave me the answer "1549799231",
whilst continuing to give "-1482656725" in the gossip messages. I'm
guessing the problem is that the gossip messages have a corrupted address,
which is why the confused node believes these messages are not for itself.
I'm using Akka 2.3.2.
