I am seeing almost continuous periodic ARC Requests demand_metadata on an otherwise idle FreeNAS Core server. I've disabled ALL services in the UI (I normally run SSH, SMB and SMART) and the pattern continues. I am not seeing any performance impact from this (presumably because all of the requests are going to ARC) but find it a bit concerning there are hundreds of thousands of requests for what seems like no obvious reason. Anyone know what is going on?

System Dataset, maybe? I get the same thing on my FreeTrueNAS Core server.
Good to know someone else is seeing the same thing. The fact that it appears every minute seems noteworthy (with a spike every 5 minutes) suggests it is some automated process. Still 500k+ requests seems like an incredible number for routine process?
