Many unsolicited data warnings

[reynir]

Running opam-mirror using cold cache dnsvizor as its dns recursive resolver results in ~1400 warnings:

[WARNING] [dns_client_mirage] received unsolicited data, ignoring

ocaml-dns/mirage/client/dns_client_mirage.ml

Line 160 in d84c3bc

| None -> Log.warn (fun m -> m "received unsolicited data, ignoring")

This possibly happens because the cache is cold and it takes a little longer to resolve things for dnsvizor than what dns_client_mirage has patience for.

Hmm, strange. Indeed it may be that dns-client-mirage is not patient enough. Does this as well happen if you use dnsvizor as a stub resolver (which should have an easier time responding to requests)?
