Lazy :) :)
I have moved the N200 over to another
cable to see if the situation improves but I think that the best
solution is to move the Ubuntu box into the shack rather than
move house/shack closer :)
The native BER of 1000BASE-T is better than 1.0e-11 or so.
Which means you'd expect a bad bit roughly every half-hour at
2msps (64Mbit/sec), the bad-bit probabilities get worse as you
make the cable longer.

Ok, Marcus, will do. Overnight (NZ time) I got 1 D with the
Atheros. I should have said that the N200 was in the shack and
the Ubuntu system in the house. I have several runs of
Ethernet out to the shack so will do some experimentation on
the different connections. Then I will move the Ubuntu system
to the shack and see if colocation helps. These investigations
will take some days but will let you know.
It's possible that we're dealing with a memory leak
somewhere. Could you watch the memory consumption of
simple_ra over time?
Also, could you just run something like uhd_fft with the
same sample rate for long periods to see if it gets the
same 'D' treatment?
