        And here. Symptoms seem to be similar to the ones which led to the upload server being taken offline last month - see Uploads disabled.

        In particular, I think it's a problem with the upload storage area behind the server, rather than the upload server itself.

          We enabled the deletion of BRP4 "tasks" (result files).

          This causes quite some I/O load for now, but should be over when the file deleter has finished its backlog.

          Edit: See Server status page: "Tasks waiting for file deletion".

              The numbers do drop. But they drop slowly.
              It seems its going to take a few hours...

                Will drop even slower now, but the throtteling should leave more I/O for file uploads.

                  I've seen the backlog dropping by about 100,000 in 40 minutes, so it should be finished by maybe 18:00 UTC - depending how much that last change slows it down.

                  But I still haven't seen a single upload going through. Many of the failures look like this:

                  - the entire file is sent to the upload server, but it then gets that 404 error from (I presume) the upstream storage server. When that happens, BOINC (without the debug logging) simply shows

                  Not even a transient error between 'starting' and 'backing off'.

                      No, and I don't think there should be. Getting more tasks at this stage would just add to the ever-growing backlog a few minutes later.....

                      It's a deliberate self-limiter.

                        SSP is saying that the file deletion is complete (0 tasks backlog), but uploads don't seem to have re-started yet.

                        Edit: still getting that 404 Not Found error.
