project 7624 (183 0 48) NAN at 1%

[kiore]

I have just had this failure on one of mt GTX 560's a NAN at 1% these things happen and would not normally be too concerned to see one every once in a while just this happened while I was watching and the card was not OCed at the time and the temps were very low for here, ambient 20c and card reading 64c .
I got the same unit reissued to me straight away and it is folding happily now although only at 8% so far, I haven't changed the config and the new version running at 65c.
I understand NANs can happen for different reasons but this one occurred in the middle of the upload, while not OCed or hot and the same unit is now running well

With v7 client uploads and downloads are asynchronous. Folding is still occuring during those processes.

P7624 (183,0,48) is not bad in that it has been successfully folded 45 times with only one failure. No, I don't know why the WU was issued to 46 people not including you but I counted them off the database.

Thanks for the report. I have manually shut down this WU - feel free to dump it. Please let me know if other issues crop up.

Thank you, the 2nd time it downloaded it ran fine to 45%, but I dumped it when I saw the above as it seems to have been done often enough.
