Out of interest, how many processing threads were chosen in GWT for the job? It may be an idea if the input page is changed to default to 2 threads and there are warnings if you have more than 8 or so. I can imagine 20 processing threads causing a server issue for large files and in practice I used 4 or 5 for my largest upload jobs; probably something to usefully add to the user guide.
I kept the by default setting of 5. My guess is that when our server get overloaded, GWToolset start making more request, those it would have done natural, and repeating those who were failing, but it’s just my guess.
