Unfortunately it's not possible to upgrade the OS at this time as the server is remote and in production. Here's the rc.conf setup: ifconfig_igb0="up" ifconfig_igb1="up" ifconfig_em0="up" ifconfig_em1="up" cloned_interfaces="lagg0 lagg1" ifconfig_lagg0="laggproto failover laggport igb0 laggport em0 1.2.3.4/25" ifconfig_lagg1="laggproto failover laggport igb1 laggport em1 5.6.7.8/16" The strange part is that this happened on two separate machine (same hardware) at around the same time but not a third identical server. Some relevant parts of dmesg: igb0: port 0xcc00-0xcc1f mem 0xfa3e0000-0xfa3fffff,0xfa800000-0xfabfffff,0xfa3dc000-0xfa3dffff irq 16 at device 0.0 on pci5 igb0: Using MSIX interrupts with 10 vectors igb0: Ethernet address: 90:e2:ba:00:d5:ca igb1: port 0xc880-0xc89f mem 0xf97e0000-0xf97fffff,0xf9c00000-0xf9ffffff,0xf97dc000-0xf97dffff irq 17 at device 0.1 on pci5 igb1: Using MSIX interrupts with 10 vectors igb1: Ethernet address: 90:e2:ba:00:d5:cb em0: port 0xdc00-0xdc1f mem 0xfbce0000-0xfbcfffff,0xfbcdc000-0xfbcdffff irq 16 at device 0.0 on pci6 em0: Using MSIX interrupts with 5 vectors em0: Ethernet address: 00:25:90:62:bd:2a em1: port 0xec00-0xec1f mem 0xfbde0000-0xfbdfffff,0xfbddc000-0xfbddffff irq 17 at device 0.0 on pci7 em1: Using MSIX interrupts with 5 vectors em1: Ethernet address: 00:25:90:62:bd:2b If anyone needs any more information or has any ideas please let me know, all that fixed it last time was rebooting, destroying and recreateing the lagg1 interface and even removing totally and creating a lagg2 with the same details had no effect at all. Thanks!
