Wow... I had gone as high as -d2000000 with no success, so I figured there was
no point in continuing to push it higher. Obviously I'm a coward ;-) But,
emboldened by your reply, I've just raised it to -d4000000, and indeed, it
starts up without errors. But as you suggest, it still drops queries. I raised
it to -d8000000 and it appears to be performing like a trooper.
I have to admit, I'm puzzled -- this machine isn't all that different from the
last one I set up, apart from the fact that it's 64-bit Intel Xeons instead of
Intel Pentiums, so it requires the amd64 OpenBSD distro in order to support SMP.
The previous machine is humming along peacefully with a setting of -d400000 with
no issues. Why would it take 20x the value for amd64?
(sorry, this may have become more of an OpenBSD question than djbdns, although
maybe not... it does seem that tinydns is affected way more than any other
service... I didn't have to do anything to get dnscache, qmail, etc. to work.)
Thanks very much for the reply... any further information is purely to satisfy
my curiosity, as my machine is now working smoothly.
Cheers,
Alex F.
