I've got dozens of these errors in syslog:
The IP 192.168.0.100 was assigned to a new host before I got the static IPs configured in dhcpd.conf. It has since been assigned a static IP and there is no device connected with IP 192.168.0.100.

I've read up on /var/state/dhcp/dhcpd.leases and man dhcpd.leases, and I get it that a dynamically assigned/leased IP address will persist in dhcpd.leases pretty much forever. But why do I keep getting these syslog messages when there is no "duplicate" assignment to MAC 14:da:e9:f4:c2:d0?

Can I make these messages stop? They're cluttering up my syslog!

perhaps?

One of the google link said to simply stop dhcpd and delete the bogus leases from /var/state/dhcp/dhcpd.leases. So, I did that. Not very elegant, but I guess that's the only way.

Glad it helped!
