Only the last few lines are relevant (and we really ought to catch these
exceptions and render them in plain text instead of HTML):

That suggests that the grid you're uploading into is full. Your client
spoke to 99 servers, asking each to hold a share, and got 99 "no"
responses. (the error message is meant to distinguish this case from
situations where some of the servers returned errors, or you weren't
connected to any servers, etc). It's also possible that your grid is
supposed to have more than 99 servers, but you were only connected to a
subset of them at the start of the upload, and the 99 machines that you
*were* connected to were all full.
