Aleksey Yeschenko commented on CASSANDRA-11090:

That doesn't seem like a problem to me - that's the way it should work. The 
original issue was causing empty hint files to be created and deleted every 10 
seconds, this seems to be processing non-empty hint files every minute, as

>             Project: Cassandra
>          Issue Type: Bug
>            Reporter: Blake Eggleston
>            Assignee: Aleksey Yeschenko
>            Priority: Minor
>             Fix For: 3.0.4, 3.4
> After the hints executor finishes sending hints, another hints file is 
> created for the same host, which is then processed on the next go around. 
> This continues indefinitely. The new hint files are empty, so there shouldn't 
> be any network traffic. However, there's still unnecessary hint activity, and 
> the hint crc file isn't deleted in the 3.0 branch after hints are dispatched 
> (but is in trunk), so any hint activity will trigger ~8640 files being 
> created per day until the node is restarted. Restarting the node fixes the 
> problem, after the existing hint files are processed. 
> This can be duplicated on cassandra-3.0 to trunk with this script:
