commit 903fb3dd62add48fa71efc4ce554f6161dc409eb Author: David Goulet dgoulet@torproject.org Date: Wed Oct 20 13:49:44 2021 -0400
relay: Avoid duplicate MetricsPort DNS error
We don't output per-type DNS errors anymore so avoid looping over the DNS query type and output each errors for them. Before this commit, it created 3x the same message because we had A, AAAA and PTR type records.
Fix on previous commit e7abab878241592e
