I suspect it might have something to do with running an MTU of 9000 on the main ethernet port which is directly feeding a workstation with an NFS root (and thus gets quite a high load at times) It's not so much an issue but it does cause the workstation to stall for up to a second while it waits for data every time it occurs. The loaded ethernet port is this one on an PCI card 0000:00:0d.0 Ethernet controller: Marvell Technology Group Ltd.
