Hi,
So I've changed the configuration last night, eliminating the possibility that the issue was LACP. All traffic was handled by the single igb interface. It didn't help, at all. This morning the interface stopped working, without any form of messages and started working again after a few minutes. Then, some minutes later it stopped again, to resume after a few minutes. So now I plugged the switch into an em-port and I tried to move the vlan interfaces to the em-interface. That worked, partially. The server kept the old mac-address in the arp-table. Even after I deleted the vlan interface. I rebooted the box, and so far so good. But still, any help is appreciated.

It's a FreeBSD box with two igb-interfaces in an LACP trunk with jumboframes and vlans. If the connection drops, the only thing I see is: Apr 1 10:37:18 zstore02 kernel: igb0: Interface stopped DISTRIBUTING, possible flapping Apr 1 10:37:28 zstore02 kernel: igb1: Interface stopped DISTRIBUTING, possible flapping The switch has nothing to say, so it doesn't seem that there are acual linkflaps. I have a feeling that it's this LACP trunk that goes haywire somewhere on the FreeBSD side. If anyone can help me with this, I'd be grateful. If someone (preferably EU-based) wants to help out professionally as a consultant, that would be fine too. Or if anyone knows someone in .nl that offers this level of expertise on consultingbase, let me know. I'm running 10.1-RELEASE on the box, see the (AFAICS) relevant config below. The switch is a Brocade ICX6430.
