[Pdns-users] Recursor 3.6: DNS parser error "All data was not consumed"

[Oli Schacher]

Hi

Since upgrading to recursor 3.6 I can not resolve some records. I've
only noticed this for a single third party domain so far (fhsmail.ch) -
how can I debug if this is a problem in the recursor on in the remote
system?
