Some quick research for you:
This page: http://fahwiki.net/index.php/CoreStatus_codes says its due to "Triggered by the OS, probably due to overclocking/overheating or a memory failure"
Also, see this page: http://forum.overclock3d.net/index.php? ... -is-alive/
Looks like it might have something to do with your RAM, but that would be pretty unfortunate so hopefully someone more knowledgeable can make a better diagnosis.

Thank you , Jesse_V
Please excuse my brief Opening Post as I was rushed , but this was just to report a bad WU.

No problem. I think it's probably a bad WU, as from the last bit of your log it seems that the next one fired up just fine. Since that one uses the same core so your RAM might be fine.

Anyway, one of the mods can come by and check to see if anyone else can complete it. F@h also has a script in place to remove the bad WUs from being passed on to too many donors, so I'm sure it'll be taken care of. Thanks for reporting it.

Is your folding name "Pick2"?

There is one report of an instant EUE in the database but it's not from "Pick2" (and it's from Windows) so this probably counts as the second report.

The one report to which Bruce referred is not for Plutronics or Pick2, so your report is the second report. Marked for followup and thanks for reporting it.

I just received this same bad WU again:

Project: 7507 (Run 0, Clone 160, Gen 1)

CoreStatus = 8B (139)
[22:37:44] Client-core communications error: ERROR 0x8b
[22:37:44]
Folding@Home will go to sleep for 1 day as there have been 5 consecutive Cores executed which failed to complete a work unit.

It tried to run 10 times and EUE'd right off the bat each time. This has been the only failure on this blade ever.

There are three failures in the WU Database so I have marked it as a bad WU:

The WU (P7507,R0,C160,G1) has been reported as a bad WU.

Thanks for your report.

I seem to have a different problem with the same WU:

I keep receiving this same WU, even after removing the Work-folder, etc. as described here http://foldingforum.org/viewtopic.php?f=19&t=16526.

Thanks--looks like it's a bad WU. We re-generated the start file, but it may take the server labeling it as bad to get rid of these.

Posted: **Wed Jan 04, 2012 2:58 pm**

When would this take place? As I would like to start my client again, and currently the client still gets the same WU and still crashes on it.

Posted: **Wed Jan 04, 2012 11:19 pm**

Mods can label a WU as "bad" but when they do, it is taken out of service at 8am Pacific Time the next morning.

By that time, I'm not sure if that would end up taking the newly regenerated WU out of service so I don't think I should do it.

Posted: **Thu Jan 05, 2012 9:37 am**

Fyi,
8AM PST (i.e. 0:00 GMT) has passed for several hours, but I kept receiving the same WU.

After following http://foldingforum.org/viewtopic.php?f ... 26#p164322, my computer is now working on a different WU.
