Just having a few problems completing this unit.
Windows XP Pro
2Gb RAM Intel e8400 (Stock)

The first run failed.

The next run I shut the client down and restarted prior to the failure and got...

After this I was lucky enough to be assigned a 3064 that completed successfully before getting the same unit.
This time I got...

Perhaps something wrong with this unit?

[kasson]

Possibly. Multiple failures on a processor running at stock speed that is successfully completing other WU's argue that the WU is at least more finnicky than most. However, the fact that it's failing at different points means that there's not one single place that reproducibly kills the WU.

[Oldhat]

Thanks for the reply kasson. If I get it again perhaps I'll be lucky enough to get it on a different computer.

Cheers

I was having multiple failures with a 2665 WU. I "sneakered" it to another box and successfully completed it. I tracked my problem down to a bad HDD. I replaced the drive with notfred's diskless CD and all seems to be working now.

[Oldhat]

Thanks for the suggestion Mobius0412. I monitor my folders at least twice a day, but will definitely be keeping a closer eye
on that box. As kasson suggested though, it may purely have been a particularly finicky WU as that PC has successfully completed
a 3064 and has just finished a different 2665.

Rather sadly it is now at 39% of yet another one.

They definitely knock the ppd for a six even after the points boost.
