A couple of weeks ago I upgraded my BINDs to 9.7.0 and enabled DLV.
This is my first time attemting to validate DNSSEC; however, I've been
seeing intermittent failures to resolve domains under .org which have
been frequent enough to force me to disable DLV again (hence
effectively disabling DNSSEC since I have no other trust anchors
configured). The queries are resulting in SERVFAIL, and I'm pretty
sure the failures are DNSSEC-related, as when I've seen problems as
they occur (dig failing from the command line) then repeating the
query with the CD bit allowed it to succeed.
Has anyone else seen similar problems? Could anyone give me any hints
as to what I can do to help debug this? I started collecting dnssec
debug logs after the fist time it happened, but am open to suggestions
as to what else I should be logging.
I attach a fragment of dnssec debug logs relating to freebsd.org from
around the time that I was having problems receiving mail from that
domain.
Thanks in advance for any help,
