FYI:

There appeared to be some trouble with this run of Project 11268. Every time I stopped/restarted the client, it came up with a fatal error and had to be closed.

Got rid of all files (moved them to the Recycle Bin) under the \work sub-directory and the unitinfo.txt file under the main directory Application Data\Folding@home-x86, then tried a restart. Seems that the it is working fine at the moment (the very same job was reloaded and is currently running), as noted in the second code snapshots below. We'll see how it runs. It should finish running in about 16 hours or so if nothing else occurs.

Thus a question on future occurrences of this, does one just delete what I removed, or should more files be removed in order for the client to work?

Thanks,

Others are reporting the same error - somethings wrong with these WUs.

Interesting. This one is still crunching, now at 66 percent complete.
Thanks for the heads up on these WUs.

So apparently this has been fixed? I saw a report that it had been but we've still been getting reports of problems. I'm confused.

Posted: **Fri Nov 05, 2010 6:45 am**

bruce, I think it is best to look at the time in the logs. My assumption is that all WUs from the 112xx Projects downloaded in a certain timespan yesterday became 'bad' for some reason. The first user posted it here: viewtopic.php?f=19&t=16581 and it was quickly fixed by yslin. But between the time the error happened, and the time it was fixed, all WUs went bad.

As long as the users try folding the bad WUs they downloaded earlier, the core will error out. They should remove their queue.dat and work folder and ask for a new WU. If they get the same WU they downloaded originally, it will fold without problems.

This can be seen from the log above, the bad WU was downloaded at:
[14:37:22] Project: 11268 (Run 2, Clone 40, Gen 17)

The user restarted the client later, and had the same problem:
[18:57:51] Folding@home Core Shutdown: UNKNOWN_ERROR

But after removing the related files, he was reassigned the same WU, redownloaded the files, and started folding without problems (2nd log file).
