Brian added an interesting reply regarding this problem:

I found this part particularly interesting:
"Generally when we see NAK patterns like that, it's a sign that something is getting overwhelmed or bottlenecked on the Expert side, and that caused the Expert to drop a lot of packets on the floor at once. "NAK" means that the Expert is requesting that Roon re-send packets that were lost. The more alarming thing is not the presence of NAK's (these are normal), but the high counts associated with them.
Occasionally, there can be other causes for this--1000mbit to 100mbit transitions at network switches are notorious for dropping UDP packets (AIR uses UDP). Buggy switches and bad network cables (both of which are more common than you might think) can also be the culprit."
I already started thinking that could this problem be caused by my switch (the Aqvox switch) or my Ethernet cables (basic cat6)....
