It is a router passing ISP traffic (lots of stuff, mostly port 80 and 
torrents....).

dev  in/out
igb0 300Mbps/200Mbps
igb1 400Mbps/100Mbps
em0 40Mbps/4Mbps
em1 100Mbps/400Mbps
em2 150Mbps/50Mbps

Rebooting 5 days ago with these tunings in loader.conf fixed the 
issue...  Thanks for all the help, FreeBSD community!

kern.ipc.nmbclusters=524288
hw.igb.rxd=4096
hw.igb.txd=4096
hw.em.rxd=4096
hw.em.txd=4096

Oh, and I ordered a motherboard with two ix and two igb devices on the 
motherboard.  That will replace this slightly older router.
