I just joined this list on the weekend, so don't know the background to
Recently I got a lot of these messages also, but we fixed it. Here's what
I have had an OpenBSD 2.6 system running at my ISP's server park for about
a year now. Last week I installed 2.8 on a newer box and took it to the
server room with plans to migrate from 2.6 box to 2.8 box. When I first
reconfigured ip, subnet, gateway, etc for the new enviroment on the new 2.8
box, it was connected to the same hub/switch/subnet as the 2.6 box, but I
got a lot of these messages and it turned out to be a routing problem in
the network, nothing wrong with my settings. We didn't exactly identify
the specific cause of the problem; we were in a hurry; my box was simply
re-connected to a new hub/switch/subnet, given a new ip addr and gateway;
problem went away.
A few days later; when the final moment came to "swap" the ip addresses of
the two boxes (to go "live" on 2.8), we swapped cables between to boxes and
settings for ip,subnet,gateway,etc. I ran into the same problem again
because I mistyped the ip address of the gateway server on the 2.8 box.
Fixed my typo, rebooted and messages went away.
Sorry if this is completely unrelated to the original problem...
