I had a blip happen to my Gateway vm yesterday. This issue occurred between 2021-04-14 17:00:10 and 2021-04-14 20:55:51. I was notified by email of the issue, the server seem to respond appropriately. The issue stopped without my intervention.

I ran the following cmd while the issue was happening with no results.

ps -eo pid,user,time,%cpu,%mem,sz,tty,ucomm,command | egrep '%|mcad' | egrep -v 'grep|ps'

I also restarted the vm during the event with no changes to the issue.

Does any one know what is the 'mcad' service?
