ICX Kill Console Not Working

[KennethDelaney]

I have an ICX7650 with 8.0.90kufi firmware with two console connections that I cannot remove via #kill console n.    When I do a #who command I can see two console connections, one over 175 days, and the kill console command doesn't remove them.  I'm sure doing a reload would remove them, but this is a Distribution switch for the core network and was looking for a sure way to kill these stale console connections.
