I have been using the updated version of DCCT - the MDCCT plotter and have had a problem.
The plotter has slowed to a crawl or stopped altogether at 95% complete. My drive is 5TB with a GeForce GTX 750 TI graphics card.

Here is input to start:

./plot -k xxxxxxxxxxxxx587 -x 1 -d /media/imbota/burst/ -s 0

Working output:

Using SSE2 core.
Creating plots for nonces 0 to 18907000 (4959 GB) using 12775 MB memory and 4 threads
95 percent done.

Does anyone have an idea as to why this might happen?
Thanks for any help you can give.
