These are innocuous. I think that, at startup, they occur when you have an up
interface that doesn't yet have an IP address assigned to it. Presumably the
recurrence is when your dhcp lease reaches its renewal period.
If you check your DHCP leases, /var/db/dhclient.leases.* these should line
up to the time of renewal.
option subnet-mask 255.255.255.0;
option routers 172.16.1.1;
option dhcp-lease-time 86400;
option dhcp-message-type 5;
option dhcp-server-identifier 172.16.1.1;
renew 3 2019/2/27 23:11:28;
rebind 4 2019/2/28 08:11:28;
expire 4 2019/2/28 11:11:28;
you'll find a few mentions of this error message on forums.freebsd.org already and in the email archives too.
