Hi Charles, [root@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. 2015. 12. 16. 0:08 keltezéssel, Charles Swiger írta: > On Dec 15, 2015, at 2:47 PM, bcs <bimmer@field.hu> wrote: >> I have 3 FreeBSD 10.2-RELEASE machines and all of them suffers of the following problem.
