What is certain is that they are not In Progress on Computer ID 1056676 - Might be a good idea to re-send them to anyone if that's possibile.... or wait for them to fall through the due date. Main reason to report is that I can find no trace of even having received the files or WU on this host/client... so it could be a server problem.

One, as you point out, is that once your tasks pass their deadlines, they will automatically be reissued. Unfortunately, one area where BOINC does not check thoroughly is the scheduler reply. The servers send the reply to a request for work and do not double check that you receive it, in full. Sometimes the internet connection is interrupted and the client issues an error indicating there was no end tag found in the scheduler reply. The projects could enable a BOINC feature to double check all of the tasks on your machine against the current list with each scheduler request, but this is a lot of overhead for a minimal gain. So, most projects do not utilize this function. So, it is an issue with the BOINC client and server code. It is one of many fairly minor issues that have not yet been addressed by Berkeley.

So long as the system sorts itself out in the end it's not a problem and the due date isn't that fare ahead (I'd probably be more concerned if the due dates were next year like in CPDN).
