That FD 23 is from the above opened socket, not the unsuccessful ::1 one.

Do you have EDNS enabled on your network? If so you should be able to
rebuilds with SNMP_REQUEST_SIZE somewhat larger to avoid these. It
should be twice what your largest expected packet size is. Our default
is 4KB for Ethernet 1.5KB UDP packets.
