Project: 6801 (Run 4394, Clone 1, Gen 2)

Sticks435, you will probably have to try this to get rid of the offending work unit.
1. stop your client.
2. delete the work directory and queue.dat file.
3. restart the client

If that doesn't work and you get the same unit again, repeat steps above AND change your machine ID to a new unique number (not used by other clients on this computer). You should then get a new work unit. Good luck!

[sticks435]

Yea, once I realized I was getting the same unit over and over, and a couple of others had the issue, I went ahead and did that (including changing the machine ID) last night. Completed 6 WU's now without issue.

The WU (P6801,R4394,C1,G2) has been reported as a bad WU.

Just had this on one of the GPU folders and I also had it at the weekend on another machine so it's still being assigned.

I also have a gpu down because of this WU. Trying to downclock it to see if I can get it working, but given the reports here, this just seems like a bad wu. It's troubling, because I keep deleting the work folders and all that stuff, and it keeps downloading it again. Guess I'll see what else I can do....

I've failed this WU about 20+ times now.. Project: 6801 (Run 4394, Clone 1, Gen 2)

If it has been flagged as a bad WU, why is it still being assigned?

This particular WU is being folded on a GTX 470 @ stock settings. Here's a snippet of one failed attempt.

According to the records that I can see, the last time this project was assigned was 2011-03-23 20:52 UTC but I only see results that are actually returned, not ones that are assigned and then never returned.

I reported it as a bad WU Wed Apr 13, 2011 16:09 UTC and, just to be thorough, reported it again just now.
The WU (P6801,R4394,C1,G2) has been reported as a bad WU. Note that the list of reported WUs are stopped daily at 8am pacific time.

Your log shows it being downloaded [May 4 03:40 UTC] That should be impossible, but I'll ask and see if somebody understands what's going on.
