Sorry, I had missed this question - no, I do not run rpc.lockd.

Answering the questions you asked the other reporter:

* no rpc.lockd
* mount options (no nfsstat -m on OpenBSD):

bora.vmnet:/exports/vmbackups/tempest on /nfs type nfs (nodev, noexec, nosuid,
v3, tcp, timeo=100, retrans=101)

* nfsstat output (system up since installing your patch):

        groups: bridge local
        nd6 options=9<PERFORMNUD,IFDISABLED>

where epair2 is the host machine running NFS and the tap interfaces are the
OpenBSD VMs. The network is on 172.16.255/24, not that it should matter in the
least, with .1 the host and the guests on .2, .3, .4.

This configuration is unchanged as of FreeBSD 14.3-RELEASE, the host was
installed with FreeBSD 14.0-RELEASE when initially procured.
