Brandon Williams commented on CASSANDRA-10371:
----------------------------------------------

bq. Double checked gossip info (ccm node1 nodetool gossipinfo) and still see node3 info.

That is normal, for 72 hours.  You should open a new ticket for any further issues.

> This may apply to other dead states as well.  Dead states should be expired after 3 days.
 In the case of decom we attach a timestamp to let the other nodes know when it should be
expired.  It has been observed that sometimes a subset of nodes in the cluster never expire
the state, and through heap analysis of these nodes it is revealed that the epstate.isAlive
check returns true when it should return false, which would allow the state to be evicted.
 This may have been affected by CASSANDRA-8336.
