Losing WU due to Power Failure

clifford_cooley

Is it common to lose WU's when the power goes out. I figured the WU would recover from the last check point.

So, this log represents the activity when restarting your Folding client after a power failure? Did your computer shut down? And is this the point after you restarted the computer that you started Folding again?

That would be correct.

Thats after the power lose when I started folding again.

From there the new A3 WU started.

I noticed later I recieved credit for the WU but lost the points.

It'll try to pick up after a shutdown, but if it's in the middle of something and the power gets cut, it's a crapshoot as to whether the checkpoint will be valid and uncorrupted.
