So far so good, nearly 500,000 tcp queries without any lingering sockets.
Good!
Totally unrelated, but I see a stat that's not mentioned in the
docs: "no-packet-error 492682". What is that, and is it any cause
for concern?
It is a debugging metric we added to see if our event multiplexing
infrastructure is operating as well as it could. Can you give me the output
of 'rec_control get-all' after some time of operation?

It is probably of no concern, but it might waste some CPU cycles. Probably
no-packet-error is a lot smaller than your number of questions and
outqueries.
Yep, total questions is 567237874, no-packet-error is 73902632, so roughly
maybe 1/6 of all questions.
Let me know if you want to see any other data...
Thanks,
Charles
I'm really happy with the recursor so far, we previously used
dnscache and we're seeing about 1/5 the cpu usage and I believe
we're also answering queries that we weren't before - our overall
qps went up quite a bit after the switch.
great!
Bert
