Joel Knighton commented on CASSANDRA-10371:
-------------------------------------------
[~pontryagin] - you're welcome to apply any patches you'd like, but this patch
will also be available in the next version released on these branches. At this
point, it will have been better tested and reviewed. If you'd just like to
resolve the issue, a restart of the affected nodes (or a rolling restart) will
clear up the issue in your case.

> 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.
