Stefania commented on CASSANDRA-10371:
--------------------------------------

[~brandon.williams] is this still an issue in 2.1 HEAD? If so can you provide 
some log files, ideally at TRACE level or some instructions on how to reproduce 
this?

>From a code inspection of 2.1, I could not see anything that would cause 
>{{epState.isAlive()}} to be true for a decommissioned node, even taking 
>CASSANDRA-8336 into account, a decommissioned node should be in state left and 
>it should have been marked as dead.

> Decommissioned nodes can remain in gossip

> 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.
