Yes. There are two possible causes.

1) That core has had a number of changes since the version you have and most likely you've encountered a bug for which a fix will be available very soon. You're running version 0.0.12 and version 0.0.17 is currently being beta tested and hopefully will be ready for distribution very soon.

2) If you're overclocking, a GPU instability might be the cause of the same error message.

You appear to be running Linux.

* Pause all active FAH WUs and wait for all FAHCore* processes to end.
* > cd /var/lib/fahclient
* > sudo rm -r Cores
* One-by-one, restart each of your slots and they should download some fresh copies of the FahCores, including a later version of FahCore_21.
(It won't be v17, but it will be a later version which fixed at least one of the possible causes of that error.)

Note that someone else has been able to complete the WU.

Thanks, it is updating the core now.
I'd expect a bug vs any overclocking issue. It failed immediately, but I am lightly overclocking that card, so could be that too. I looked back through my logs, and the only other error for the entire month of December was on 12-DEC-15 of the same type. Potential Energy error on 9211-0-69-10. It also failed immediately before showing any work percentage completed.
