Can you get the output of netstat -I emX -d?  You don't need to run
that when the problem is happening -- you just need to run it on the
machine after it exhibits the issue without any reboots in the
interim.

I suspect that you are seeing the em TX queue fill up.  If so you
should see output drops reported by the em interface.
