[-- Attachment #1 --] Hi, I've got an urgent matter on my hands, my FreeBSD iScsibox has dropped it's LACP trunk twice in the last 24 hours, which causes a whole lot of issues on my VPS cluster, using that storage. 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.
