I have just upgraded two C9300 edge switches in our DNA lab from 17.3.5 to 17.6.3 as this has now gone 'Gold Star'. I also marked the four recommended 17.6.3 SMU patches as 'Golden', so these have also been applied. Now consistently every minute I get this on the console/logs of both switches:

I searched on here and there is a bug from 2013 with the same error (CSCum86316), however it seems to be for previous generation series Catalysts (2960S & 3750X) and much earlier software. Think I might have to downgrade them back to 17.3.5.
