FreeBSD 11.1-RELEASE-p1 December 1, 2015 FreeBSD 11.1-RELEASE-p1 I'd guess you could get an error from something as benign as a collision or anything else that forces a retransmit by my math this is on the order of .001610031% of your traffic. with that low of a total count and percentage, I wouldn't think it makes much sense to chase down much farther unless you have a specific issue you're trying to work through. -- public gpg key id: 0x5B8147CB
