So far no one has returned this WU, successfully or otherwise.

Members of our team have received this WU ten different times,
with the same result every time.

Guess what, the Fahlog report is identical to that of DocJonz.

The following link points to a list of WUs that has been troublesome to our team.

One of my other Linux boxes has tried to pull this WU down today - exactly the same outcome as before ....

Thanks for the reports. We're looking at ways to deal with such problems better; the concept is easy, but the implementation is hard, so it may take a while. :(

Project: 3059 (Run 4, Clone 75, Gen 25)

Got this WU again today.

Same results as always, immediate failure.
