Had this die on me twice over the last 12 hours on one machine with error "CoreStatus = FF (255)". No problems with other projects.

I received this unit last night. When I checked F@H today I found that it was taking 90 minutes per %. Checking the bonus calculator, this was forecast to complete in six days, against a final deadline of three days. Not good.

I tried restarting F@H, and restarting my Mac, but performance remained pathetic. So I stopped F@H, discarded the work folder and queue, and restarted it. I now have a P6025 unit which is folding at a reasonable rate. I don't cherry pick, but this seemed to be faulty behaviour.

I'm not sure what's wrong, but there are strong indications this is a bad WU, so I'm reporting it. (A third person got a very small credit for an EUE report so that makes three entirely different symptoms.)

I've got it now...my step time is 1.07. So far it is at 40% but won't complete the deadline of 3 days.

As suspected, it didn't make it anywhere close to the deadline. The last portion of the log file:
