OK it ran overnight, 4338 cycles of the code, 4338 good reads on every sensor. A reliable network again!!! This was using the Sheepwalk RPI2, which is my preferred option. I will try again with the USB adapter but I am confident that will be OK as well.
It seems that the problem was with my 2 X 2 channel I/O box. Ironically when that was connected I had less than 1% errors on that, but more than 25% errors on other devices.
