I commented out em from the kernel and loaded up a previous version via kld, but still the same thing, although not nearly as much 0[smtp2]# arp -na | wc 89 680 5081 0[smtp2]# em0@pci0:0:4:0: class=0x020000 card=0x387010f1 chip=0x10768086 rev=0x05 hdr=0x00 vendor = 'Intel Corporation' device = '82541EI Gigabit Ethernet Controller' class = network subclass = ethernet cap 01[dc] = powerspec 2 supports D0 D3 current D0 cap 07[e4] = PCI-X supports 2048 burst read, 1 split transaction em1@pci0:0:5:0: class=0x020000 card=0x387010f1 chip=0x10768086 rev=0x05 hdr=0x00 vendor = 'Intel Corporation' device = '82541EI Gigabit Ethernet Controller' class = network subclass = ethernet cap 01[dc] = powerspec 2 supports D0 D3 current D0 cap 07[e4] = PCI-X supports 2048 burst read, 1 split transaction >That almost looks like some kind of ARP storm, sans repetitive entries >(that definitely looks odd).
