Is anyone else out there running a sendmail server on an AMD64
platform with OBSD 4.5? I would like to know if this is a problem
with my setup, or with the release, at least. (I doubt that is the
case, but I don't have a free amd64 system to play with, and I would
just like confirmation).
The OpenBSD stance on virtualization is pretty much "don't", and this
issue is obviously not showing on real hardware (sendmail on amd64 is a
very common setup, after all).
That said, there are people who do run OpenBSD via Xen, so it is
possible.
One thing to note is that OpenBSD can only run as a guest with hardware
support (Intel VT/Vanderpool or AMD-V/Pacifica); so-called
paravirtualization doesn't work. If you do not have the required
hardware - and you can see whether or not you have it in the Xen logs -
you could use qemu. It's slower (although not *that* slow if you use
kqemu) but known to work.
I'm not sure if Xen uses the hardware support by default; you might want
to look into that, too.
Once the system appears superficially stable, try compiling /usr/src -
it's a good test of a large number of subsystems.

Well, it ran poorly under vmware... and it seemed to work great under
Xen, until this showed up. Everything else worked fine -- it is just
the sendmail issue, and only with large emails. I can move large
files back and forth just fine via http and sftp.
Yes, I do run it as an hvm, and I have an AMD/Pacifica compliant chip
-- no issues there. It is rock solid with this one exception. I have
another built as web server, and again, no issues.
I'm not entirely sure what you meant by "hardware support", when you
say "not sure if xen uses the hardware support by default".
My biggest problem is that I cannot get it to create any error output
anywhere, not in the xen logs, not in the qemu logs, not in
/var/log/messages (on either dom0 or domu), not with sendmail running
in the foreground and not in /var/log/maillog (on domu)... It just
dies Very frustrating!
I was following the stable branch, and I have actually compiled
/usr/src -- twice now, it was about 18-20hrs of compiling but went
without a hitch. It is just this one issue that takes it down - 100%
of the time.
Maybe if you can clarify what you meant by "hardware support", I can
follow that lead... otherwise, I... I think I'm hosed...
I appreciate the input. Thanks.
