Presumably either cassandra is somehow connecting to the wrong port, or this is a firewalling/os/network issue, or the 'other' cassandra is not listening on the port. Using tcpdump/netstat -nlp should narrow that down. Is it possible connections only succeed in one direction for example? --=20 / Peter Schuller
