No, msieve is failing before it even attempts to build the matrix using TD. Or so it appears.

Too few cycles is affected by TD. It's pretty close to building a matrix. 20-40 TD lower should definitely build, though maybe as few as 5 lower will build.

I have put on 50MQ of extra sieving, which I suspect will finish in well under 1360 hours and make your life easier.
