Re: Periodic network outage

["Andreas Freyvogel" <afreyvogel@ecmarket.com>]

We had a similar type of problem a while back which may or may not apply to
your situation. We had our NIC added as a module and not built into the
kernel. So when the machine was not active, or at least the NIC was not
active, the module would be unloaded and cause a similar problem.

Hope that gives some help or at least an idea for you.

Subject: Periodic network outage


Hello,

Forgive me if this has been covered before; I'm new to the
list.

I'm having problems with my OpenBSD 3.0 machine that are
very strange.  It seems that every one and a while (perhaps
daily), my machine does not respond to or generate any
network activity for hours at a time.  I've traced the
problem to the machine itself, as I can ping other machines
on my subnet as well as my gateway.  However, the OpenBSD
machine simply doesn't respond.  After a few hours, it'll
mysteriously be back in action, with nothing showing in the
logs to give me any hints.  I can reboot the machine while
it's not responding, and of course everything works fine
again once it's back up.

Is this a known issue?  If so, is there a description of the
problem somewhere that I can read to help remedy it?  Here's
some output from dmesg:
