Hi Nelson, that’s very useful. However, can I get a full coredump?
I can’t reproduce the problem locally: # host www.unesp.br 200.145.86.1 Using domain server: Name: 200.145.86.1 Address: 200.145.86.1#53 Aliases: Host www.unesp.br not found: 5(REFUSED) Perhaps also a packetdump that could trigger the crash would be useful. Also, can you directly report this to the upstream issue tracker - https://gitlab.isc.org/isc-projects/bind9/-/issues? I am also upstream and it would be useful to have this crash directly there instead of in the Debian BTS as it doesn’t seem to be directly related to the packaging.
