See here:

The first host successfully finished the WU with the first(buggy) app which caused validation errors quite often.
The second host didn't finish in time.
Then my host(the third one) got the WU and crunched it with the Linux beta app.
The validator found a difference, so it sent it out again to the fourth host, that didn't finish so far.
Some hours later the second host finished the WU(with a buggy app too). The validator found, that buggy results from host no. 1 and host no. 2 are equal/similar.
These two got credits, my host didn't. Well that's wasting time, because another host ist crunching this WU again for hours and also will get no credits for it, as it is using the newer bugfixed app.

In this special case the validator should wait until all results are back and then decide which results are valid. 2:2, ok send it out to a fifth host. ;)
No not really. ;)

I know, this is a pretty rare situation and the results of the first app are not necessarily buggy, just different.

I hope, the wasted time in the S5R2 run will shortly tend to zero.

i have something similar, but it's invalid due to using another OS
see here
i have XP home and they crunched it using darwin 8.9.1
well, darwin=darwin=>Valid ; XPhomeDarwin=>InValid :(

Yep, Darwin and XP don't seem

Yep, Darwin and XP don't seem to go too well together, especially with the old Windows app. I had a case when I crunched with a Darwin and a Linux host with my XP box and their results validated while mine didn't.
Michael, that is really quite an extreme case you describe there...

another workunit with

another workunit with validation problems
im lucky, because third WU was sent to WinXP
but i have another WU (not crunched yet) waiting to be validated with Darwin
should i abort it or crunch it and hope, that third WU will be sent to Win?

Hi!

I'd let it crunch. It's not that Darwin and XP never agree on a workunit, my Darwin system has validated successfuly against XP systems running 4.17 and even 4.13 of the app.

Success is everything before

Success is everything before validation. It does not mean valid. It's not the best english word to use, but for translating purposes to other languages it's the better one that Berkeley found.

They have been trying to change that state if a result is invalid in the last couple of backend revisions, but as you see it does not always work.

Paired my windows with a Mac not good, now a Linux got it. Wonder who get the credit and who get none. Hopefully the staff will correct this soon, don´t care so much about the credit but think the wasted time both for me and the project sucks.

Here's a good one. All three

Here's a good one. All three hosts are Core architecture, one running XP, an other OSX, and mine LINUX 2.6.20.

Guess which one doesn't validate? ;-)

There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers. - Richard Feynman

This points to a problem with the mathlib linked to the Win-app.
But this also can mean, the Win mathlib is the more accurate one. ;-)
