	For many hours, I've had a workunit showing unusual progress numbers: Long runs (8-12 hours on fastest card) 6.16 (cuda31) I4R57-NATHAN-RPS1120528-2-166-RND7359 Running 0.185 CPUs + 1 NVIDIA GPU 5000000 GFLOPS 00:41:51 (CPU at last checkpoint) 19:19:11 (CPU time) (slowly rising) 70:45:57 (Elapsed time) (and rising) --- (Estimated time remaining; not changing) 99.960% (fraction done; not changing for several hours now) Is there something wrong with this workunit? Or is this just the way that application handles a serious underestimate of the time the workunit should run?

	that sounds like there is something wrong there. Have you tried re-starting your computer?

	I have now. Lost everything done since about 52 hours. One of the many GPU workunits downloaded during that situation took over.

	It now restarted and completed successfully. Returned not quite 4 days after it was sent.

I've had one get stuck before like that, and a simple restart fixed it. Getting stuck at that percentage seems to be something to do with writing the completed file to disk before transmission. Background task preventing disk writes perhaps? virus scan or something like that. I'm not sure.....

	There might be a larger issue here. Two of the I1R45-NATHAN_RPS work units failed for me: http://www.gpugrid.net/result.php?resultid=5479036 http://www.gpugrid.net/result.php?resultid=5478382 ____________ Thx - Paul Note: Please don't use driver version 295 or 296! Recommended versions are 266 - 285.

You should follow the outcome of those workunits on other hosts to see if it's the workunits' fault. However, I've caught a PAOLA_1H46-15-20 running (at 99% GPU usage) on my PC for more than 20 hours, while the progress indicator was showing 9.23%. I've paused and restarted this workunit, and its running time indicator dropped back to 45 minutes, and the progress indicator to 9%. Since then it's running fine (1h14m, 13.4%)
