My server recently started "pausing" every so often for a few seconds.  I first started noticing it when streaming media to my Nvidia shield TV.  The media would just freeze (since the data flow from unraid stops during this time) and then a few seconds later it would resume.  This can happen several times per hour.

 

Investigating this further, I noticed that if I'm in the web GUI when this happens, the whole GUI locks up.  The CPU load bars stop moving, I can't click on anything.  I wait about 10 seconds and everything comes back to life.  Then I looked in the server log and noticed what looks to be the NIC periodically having "hardware unit hangs".  This is the onboard NIC for my Gigabyte X99-UD3P-CF motherboard.  I have not tried putting in another standalone NIC yet as I wanted to see if anyone could have a look at the logs first and tell me if the NIC looks to be bad, or if something else could be causing this?

 

I've attached a snippet of the log file for reference.

 

Thank you in advance for any advice!

Unraid Log Nov 28.txt

So I added in a Broadcomm BCM5751 Gigabit PCIe x1 card.  Seems like everything is working fine but this morning I see hundreds of the following entries in the system log...  does anyone know what is going on here??
