Hey Chris: Thanks as always with your prompt replies. I have an ongoing problem,
Re: OS 8/9 version of 3.5 server?

however.
I generate mailing lists on an NT server using the built-in SMTP Service. The
lists are in the 10-50K email range. When I initiate a list, the outgoing emails
are spooled in a "queue" folder and sent out based on the maximum number of
connections allowed in the SMTP service (the default is 100). Spooling seems to
take up most of the server's resources so the emails don't go out en masse until
after that completes.
The primary DNS defined in the NT server's TCP/IP settings was a Mac WGS
7250/120 running OS8.6 and QDNS 3.0.1. QDNS is allocated 8 meg of RAM. The first
few times I tried to generate a list the DNS server immediately "unexpectedly
quit" as the NT server started querying the DNS. After much fiddling I reduced
the NT Server to 16 SMTP connections and the server continued to crash.
At the same time, I noticed that when I ran website log analysis reports using
WebTrends NT, with WebTrends set to resolve all IPs, the same thing would
happen, until I "throttled back" WebTrends to resolve only 50 IPs at a time.
I came to the conclusion that the TCP/IP stack on the DNS was crashing and
forcing QDNS to quit. I also thought the server might be too slow and lastly
that it might be a QDNS issue. Since then, I switched the DNS to a 7300/200,
running OS 9.1 (clean install), and lastly upgraded QDNS to 3.5. This
configuration ran stably for a week.
I then rebooted the DNS and ran a test distribution with 500 emails...after the
NT Server (still set to 16 outgoing connections) spooled all the emails I noted
a big increase in activity on the DNS, but the test passed without incident. I
ran a second test with about 1500 emails, and the server seemed OK.
I then went ahead and let the rest of the list go, about 34000 emails. It took
about an hour to spool, and after completion QDNS unexpectedly quit shortly
thereafter.
So I've tried new hardware and software, but something's still killing off
QDNS...where should I go from here to debug?
TIA, Andrew Kagan
