I'm running OS X Server (5.2 on 10.12.2) on a Mac Mini late 2014 with 8GB RAM and 2.6GHz i5. The load is always around 3.5 - 6 even without any application running. Even in top as root, I cannot see any process that uses lots of CPU time.
The server runs some services in our office of 10 people.
- File Sharing for 1 NFS host
- Calendar & Contacts
- Profile Manager with VPP and DEP (MDM) for 10 phones and macs
- VPN for the admins (so maybe once a week a login)
- DNS for the local network with 1 zone
- Open Directory for MDM and another backup NAS
Time Machine is backing up the server but other than that there is no software or service running.
I'm pretty sure it started with the latest Sierra and OS X Server update or at least I never saw it happen before.
system.log looks normal with some launchd messages from quicklook every 5 minutes but nothing unusual other than that.
All other logs look normal with no continuously repeating error message or something like that.
iostat looks normal:

and last but not least the top line from top

Any ideas where to look or what happens?
Edit: To clarify, there are no running processes explaining the high Load averages. And in my experience something like this could come from corrupt memory or hdd.
uptime 19:35 up 2 days, 6:19, 3 users, load averages: 5.17 4.96 4.54
Is there anything else to look than the logfiles?
All my linux based SMP servers run on loads of 0.xx and I'm a bit afraid that there is a bigger problem somewhere.
