Can you get the output of netstat -I emX -d?

I suspect that you are seeing the em TX queue fill up. If so you
should see output drops reported by the em interface.
I do see 205 in the 'Drop' column. I ran the command twice two hours
apart... I am seeing Ierrsincrement in a 2 hours window...

Checking all the interfaces, there are a lot more drops/Ierrs on em2...
The igb devices (PCIe card) seem a lot better than the Supermicro
motherboard em devices. Is this an on-board vs mb thing, or em vs igb
thing?
