@szolin commented on GitHub (Jun 24, 2019):

Can you enable verbose logging? (Set verbose: true in yaml config file.)

I think it crashes because there is a nil dns.RR object inside Extra[] array. Without logs I don't see which code could make such request.

func (dns *Msg) IsEdns0() *OPT {
...
	for i := len(dns.Extra) - 1; i >= 0; i-- {
>>>		if dns.Extra[i].Header().Rrtype == TypeOPT {
