It sounds like you're running into https://issues.apache.org/jira/browse/CASSANDRA-3351 so the first step would be to upgrade to a version that has it fixed. Unfortunately, this won't solve the problem, just prevent it from happening in the future. To remove the old nodes, you can apply https://issues.apache.org/jira/browse/CASSANDRA-3337 on one node and call the JMX method for the unreachable endpoints. -Brandon
