A restart of node1 fixed the problem.

The only thing I saw in the log of node1 before the problem was the following:

InetAddress / is now dead.
InetAddress / is now UP

After this, the nodetool ring command showed node as dead.

You mention a "stored ring view". Can it be that this stored ring view was out of sync with
the actual (gossip) situation?

Without knowing too much more information I would try this...

* Restart node each node in turn, watch the logs to see what it says about the other.
* If that restart did not fix it, try using the  Dcassandra.load_ring_state=false JVM option
when starting the node. That will tell it to ignore it's stored ring view and use what gossip
is telling it. Add it as a new line at the bottom of

If it's still failing watch the logs and see what it says when it marks the other as been

I have a cluster with seven nodes.

If I run the node-tool ring command on all nodes, I see the following:

Node1 says that node2 is down.
Node 2 says that node1 is down.
All other nodes say that everyone is up.

Is this normal behavior?

I see no network related problems. Also no problems between node1 and node2.
I use Cassandra 0.7.10
