Created attachment 306527 [details, diff] Work around the crash. net-dns/bind-9.9.0 will crash if there's at least 2 views configured, and the latter one used the NXDOMAIN redirect functionality. Reproducible: Always Steps to Reproduce: 1. emerge bind-9.9.0 2. Start bind using below test config: # vim: set filetype=named.conf autoindent ts=4 sw=4: options { directory "/var/"; pid-file "file-named.pid"; dump-file "file-dump"; recursion yes; }; view "area-1" { match-clients { 1.1.1.1; }; zone "." { type hint; file "named.cache"; }; }; view "area-2" { match-clients { 2.2.2.2; }; zone "." { type hint; file "named.cache"; }; zone "." { type redirect; file "nxdomain"; }; }; And the file "nxdomain" content: $TTL 60 @ IN SOA localhost. admin.localhost. ( 2012032100 ; serial 1D ; refresh 1H ; retry 1W ; expire 3H ) ; minimum @ IN NS localhost. *. IN A 127.0.0.1 And start command is: named -u named -c /etc/named.conf -t /path/of/chroot/ -g 3.
