Oh yes, I did a update and upgrade to the RPi, before I did that it was running like a champ. Indeed I had upgraded WeeWx on it a while back and did a gen- eral update/upgrade to every thing back then. So something came down the pipe that broke this thing and I am not sure what as it has been running great ever since I started using it to pull the weather data off of my Costco weather box.
I do see a lot of IPv6 stuff happpening, so I am suspecting something to do with that but not sure.
