I think this error is the same as this http://www.mail-archive.com/user@cassandra.apache.org/msg06295.html

It also occurs when the GCInspector is doing it's thing and is nothing to worry about.

Do you have any firewalls etc between the nodes?

After looking around the config, I changed the rpc to the individual machines addresses (ill give 0.0.0.0 a try next). This hasn't helped. I checked out the log and discovered I get this error whenever I try to start the server...

What setting do you have for the rpc_address ? I use 0.0.0.0 to bind to all interfaces, you may want to set it to your ip_address listed.

my example

# Address to bind to and tell other nodes to connect to. You _must_
# change this if you want multiple nodes to be able to communicate!
listen_address:

# The address to bind the Thrift RPC service to
rpc_address: 0.0.0.0

I'm having some issues getting three nodes to cluster together in .7 beta 2.

Seed: xxx.xxx.xxx.xxx
other node Y: yyy.yyy.yyy.yyy
other node Z: zzz.zzz.zzz.zzz

when starting node Y this is the output... As you can see it binds thrift to localhost even though its set as the machines ip in the cassandra.yaml file. (i had already started the seed node which also bound thrift to localhost and not it's ip.)
