Jonathan Ellis commented on CASSANDRA-713:
------------------------------------------

you're going to need to post the rest of that stack trace, probably to a different ticket.
 it doesn't look like it's related to jaakko's.

> I took a node offline last week and then attempted to re-bootstrap its token range with
a new cassandra install on the same IP. I made gossip forget about the node by restarting
all other instances, then brought up the new node. It said was bootstrapping, but it never
finished bootstrapping after several days. The node never showed up in the ring, but when
I take it offline, I get the following exception continually from all other nodes in the cluster:

ring.
