I found a lot of comments on this, but they all state that this is due to a too low setting for mbufs in FreeBSD8/9 settings. However, I have 10-stable here, and the settings look rather high to me: kern.ipc.nmbclusters: 1014856 kern.ipc.maxmbufmem: 8313700352 kern.ipc.nmbufs: 6495090 kern.ipc.nmbjumbop: 507428 kern.ipc.nmbjumbo9: 451047 kern.ipc.nmbjumbo16: 338284 FreeBSD mclane 10.0-STABLE FreeBSD 10.0-STABLE #5 r261710: Mon Feb 10 16:55:29 CET 2014 root@mclane.rt.aei.uni-hannover.de:/usr/obj/usr/src/sys/GENERIC amd64 Is this still too low? I have a 6core machine with 6 igb interfaces, and I cannot even get one of these set to mtu 9000 without getting "Could not setup receive structures". cu Gerrit
