Hello all,
I seem to have stumbled on problem and I just can't see a reason for it.
One of my FreeBSD 7.0 machines stops responding on the network, the
strange thing is you could set your watch by it. approx every 5 minutes
for 5 minutes it will not respond on any interface.
I've googled around but not having a clear idea of what is going on its
hard to narrow down the search and the only two things I have in
/var/log/messages are as follows:
May 26 11:49:14 zeus kernel: arplookup 192.168.0.1 failed: host is
not on local network
May 26 11:49:14 zeus kernel: arpresolve: can't allocate route for
192.168.0.1
May 26 11:49:14 zeus named[686]:
/usr/src/lib/bind/isc/../../../contrib/bind9/lib/isc/unix/socket.c:1179:
unexpected error:
May 26 11:49:14 zeus named[686]: internal_send: 192.36.148.17#53:
Invalid argument
The machine has two internal NIC's setup like so, with the second
address on both cards being an alias.

The machine is acting as a router/gateway between 192.168.0.0/24 and
10.0.0.0/8 running routed -s and gateway_enable="yes"
