It looks to me that you're getting a ton of input drops. That's presumably the cause of your issue. You can get the em driver to print debug information to the console by running: # sysctl dev.em.3.stats=1 # sysctl.dev.em.3.debug=1 The output should be available in dmesg and /var/log/messages Hopefully that can shed some light on the nature of the drops.
