Subject Re: Commit log fills up in less than a minute

So, I restarted the cluster (not rolling), but it is still maintaining hints
for the IP's that are no longer part of the ring. nodetool ring shows things
correctly (as only 3 nodes).
When I check thru the jmx hintedhandoff manager, it shows it is maintaining
the hints for those non existent IP's. So the question is
 - How can I remove these IP permanently, so hints do not get saved?
 - Not all nodes see the same list of IP's
