Hi Charles,

[root at myhost /]# sysctl -a | grep arp
net.link.ether.inet.log_arp_permanent_modify: 1
net.link.ether.inet.log_arp_movements: 1
net.link.ether.inet.log_arp_wrong_iface: 1

I am all ears if you can give me hint how to tune the network if it's 
not ok. Buggy NIC is very possible, I have other problem with "em" 
driver. The server has Intel® 82579LM nic.
