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.
