So how are you starting dhcpd *as a daemon*. Systemd?
What does the command line look like?
[0:root at bb8 ~]$ ps aux | grep dhcpd
root 20586 0.0 0.0 119524 1004 pts/3 S+ 06:14 0:00 grep --color=auto dhcpd
dhcpd 22665 0.0 0.0 139796 26832 ? Ss Feb27 0:13 /usr/sbin/dhcpd -f -cf /etc/dhcp/dhcpd.conf -user dhcpd -group
dhcpd 31924 0.0 0.0 141492 28936 ? Ss Feb13 0:24 /usr/sbin/dhcpd -f -6 -cf /etc/dhcp/dhcpd6.conf -user dhcpd
-group dhcpd --no-pid
