Yes. They have all been HDC WU's. In particular the WU's have been: B05528_ 0047_ CTMA3B1-6-10-9-c2,B05517_ 0081_ CTMA3A1-6-14-24-c1, B05504_ 0073_ YTMA10B1-4-11-13-c2, and B05503_ 0248_ YTMA10B1-4-6-23-c1.

Others have been able to run these WU's with success. I can't figure out why these WU's suddenly started failing across my machines. I pretty much leave these machines alone and let them do their own thing and have not modified them in any way prior to these failures. The only differences between how these machines were configured before( when WU's seemed to work fine) and now is an update to the latest XP patch and an update to the Symentec Antivirus signatures. These updates have never bothered Boinc in any way before, so I am hesitant to blame any weirdness on the updates.

Thanks again.

Such updates can and do cause problems, but pinning them down is hard.

Have you noticed anything else unusual, such as your antivirus software logging or reporting any interventions? If I recall correctly, Symantec report such things in the Windows Event Log.

Well, it's over to the WCG techs now. If you want a faster response, send email to the support address (but bear in mind it's almost Thanksgiving).

Meanwhile, make a note of any troublesome work units then abort them. Also consider removing HDC from your project selection.

I had the same issue with my recent units.
My normal process time recently is about 12 hours.

On these units it was at 12 hours or so and only 4% complete.
I aborted them. Hope this helps track down the issue/corrupted units.
