wuid=237465654

Just came across this WU in one of the queues...

Too bad the host that claimed 1374.19 credits errored out. Wasted 80 CPU hours for nothing :-(

Just coincidence that both failures were AMD's ?

Yep, this has been seen before and has happened on Intels as well.

Fortunately it's not like it happens a lot, but that doesn't make it any less annoying when it happens to one of your hosts! ;-)

Hi John.

Yes, just a coincidence.
There's a thread a few months back that talks about the same thing. It's a petty rare event, but either it will complete and error-out, or it will seem to run forever and a person has to abort.
These WUs would show something like 3-4% complete and an unusually huge number of hours to completion. The consensus was to abort if you noticed any of these.
Seems the AMDs got a couple @ same time.

Book him, Danno! Another point with this wu - One of the other hosts had a client error yet done claiming 40.87. How is this possible? I thought with Client Errors, one lost the credit?

Whether there is a claim or not depends on the type of error which occurred. Some will still make a claim, others don't.

Since they all result in no granted credit, I never bothered to categorize which kind do what. ;-)

No more problems with that WU... Crunched and verified!

Thanks all.
