Hi,
I have an OpenBSD 3.2 box. It's an AMD K5 150Mhz, 21Mb RAM with a
D-Link DFE-530TX NIC. I run a FTP on it.
It can run smothly for months, until there is a lot of traffic on it.
The network just dies when that happens. The machine seems tu run
normal, but no traffic can go in or out. I can't even access with SSH.
But when I log in locally on the machine and reboot the thing, it
works again until the next time the networktraffic-load gets very
high.
Does anyone know what causes this? I don't even know how to
troubleshoot this problem. Where do I begin? Does anyone know how to
fix this?

Any suggestions are welcome.

Is the system overclocked? Does the processor fan work properly? I've
seen similar faults on a system where the processor fan did not work
anymore.

The system is not overclocked. The fan works properly.
Could it be a heat related problem? The machine is not hot, but it
could be colder though...

Could be. Start measuring temperatures. Check the ram, maybe you have a
faulty ram somewhere.

OpenBSD allocates a fixed number of network buffers and
it is my experience that once that number is exceeded the
whole network stack stops working. FreeBSD is basically
the same. Look for errors in /var/log/messages. It would
be better behaviour if the kernel would drop packets while
there are no spare buffers and later recover when some
become available. You can help by increasing the number
of network buffers either by setting the option and recompiling
the kernel or by using the config utility. See the FAQ
chapter 11.

I checked /var/log/messages... I know the exact point in time when it
happened the last time. So it was not a big deal to trace it in the
file.
There is nothing there. It only says something about something that
happened 6 hours before. Then the next thing is that I rebooted the
server (after the problem). So it should be inbetween these two
happenings.

If OpenBSD runs out of network-buffers, is it recorded somewhere?
Should I just increase the buffers and hope for it not to happen
anymore?

Thanks.

I have the same problem, and my compaq pentium 200 mmx is very cold and is
the standard pc. If i don't work with this in 10 or 15 minutes, the ping to
the ip adress is imposible, i touch the keyboard and restart automaticaly
the network.

Some ideas. Tx.

Ferran

some weird APM setup? can you disable it at all in the BIOS?
anything else but the NIC is working? does it then react on ifconfig
commands still?

My Compaq does the same. You need to disable apm. Do the following:

config -e -o /bsd /bsd

Now reboot the box.

Thanks for your answer.

I see the irq 11 is the same for 3com and VIA VT83C572 USB.

I change this and probe.
