This host is also getting an mix of cuda31 and cuda42 tasks.

Hasn't had an error since i installed the GTX560 in it and started running GPUGRID again.

This certainly shouldn't be.
We set up for the first time a boinc parameter that creates n (2 in our case) results for a single WU. This improves by 50% the turnover for us. However, we checked the documentation and we understood that every result would get credit independently of the order of arrival.

If that's not the case we'll cancel these WUs.

Our intention is to grant the 100% of the successful results done within the 4 days.

I don't think this has to do with this new parameter since the initial replication shows up as 1. The WUs with the new parameter show up with initial replication of 2, in my opinion. I got a couple of those today.
I think the explanation given by Clownius is more likely what happened.
Unfortunate but hard to avoid if there the gap between overrun and resend is very small for WUs with runtimes between several hours and several days (depending on the GPU).

I completed the following WU without error (at least by http://www.gpugrid.net/workunit.php?wuid=305073):
http://www.gpugrid.net/result.php?resultid=413618

But i didn't get credit for it. Ok somebody else was faster, mainly because he got the WU sent earlier.

Why was the second WU sent out if first didn't error out or was overtime ?
