We removed this node from the ring successfully in 0.7.4. It stopped showing in the nodetool
ring command. But occasionally we'd still get weird log entries about failing to write/read
to IP

It's still going strong this morning, on day 5:

5 days seems excessive unless there is a very large amount of data per
node.  I would check nodetool netstats, and if the streams don't look
active issue a 'removetoken force' against and accept that
you may possibly need to run repair to restore the replica count.
