I know the CARP interface's MAC address is generated by the VHID so I am
sort of leaning towards it be an ARP issue and possibly not an issue with

I have a suspicion... what kind of switches are the OpenBSD hosts in
question connected to? If they are managed switches, have you looked at
the logs on the switch?
Some switches interpret CARP (and VRRP, for that matter) as either an
attack or a misconfigured system, and will temporarily block traffic to
one of the two ports. Essentially, they think it's "MAC flapping"...
which it sort of is, in fact.
