There is nothing back for that one so far. I flagged it so we'll be reminded to check on it.

Hi davidcoton (team 0),
Your WU (P9411 R1718 C0 G54) was added to the stats database on 2015-05-06 22:04:17 for 46086.4 points of credit.

[davidcoton]

Interesting. Looks like the bad WU error coincided with a Windows crash. On recovery, the same WU was restarted and ran to completion. I'll need to check Windows logs sometime to see if there are any clues.

[billford]

I've seen that, very occasionally- if something goes pear-shaped while a checkpoint is being written out, the WU will simply (attempt to) restart from scratch.

[bruce]

After certain types of errors, the client will request a new WU and occasionally the servers will give you a new copy of the same WU. That logic is not new.

In addition, there has been an unannounced enhancement to future versions of some GPU cores which recognizes that certain (rare) types of errors can be fixed by restarting from the previous checkpoint, with the loss of very little progress. This will happen automatically. The only time I've seen it restart from scratch without downloading is when no checkpoints have yet been written.

Neither of these options appear to coincide with the log extract that was posted so technically we're off-topic.

[davidcoton]

I found nothing useful in the logs, possible original error was 0x00000116 which seems to be video card related. Card is normally stable, not overclocked, etc. No application errors so the cause remains a mystery, just hope it is random and not a h/w failure (old PC which runs my business, new GTX980 GPU).
