Dhcpd fails with configuration error on VLAN
I have a pair of pfsense boxes doing CARP just fine as long as I only have one LAN interface, but when I define a second interface as a different VLAN on the same LAN interface, and add dhcp for the second LAN, dhcp stops working, and the log shows:
/status_services.php: The command '/usr/local/sbin/dhcpd -user dhcpd -group _dhcp -chroot /var/dhcpd -cf /etc/dhcpd.conf -pf /var/run/dhcpd.pid igb1 igb1_vlan42' returned exit code '1', the output was 'Internet Systems Consortium DHCP Server 4.3.4 Copyright 2004-2016 Internet Systems Consortium.

I deleted all the VLAN interfaces, and recreated everything. Now dhcpd keeps up, but pool status shows "normal" for the main LAN dhcp, but "unknown-state" for the VLAN on the primary, and " recover-wait" and "unkown-state" on the secondary.
Update: 2 rounds of rebooting both boxes seems to have gotten everything working.
