    I've got one (*) finished O1 all-sky task that doesn't upload any of the three result files and also doesn't seem to show up in my E@h tasks list. Other O1 tasks from this client did upload since then.

    Maybe it's just coincidence, but roughly at that time I got this work unit, another (545985186 , h1_0051.70_O1C01Cl1In1__O1AS20-100T_51.8Hz_56) was downloaded without deadline. It was running in high-priority right away. I aborted that one.

    (*)

                  That's one of the strange cases I wanted to investigate. It turns out the result this host tries to upload was already reported and got validated. That's why any subsequent upload is prohibited. I really would like to know what happened on the Client that the file size increased and the Client thought it needs to re-upload the file again (or the part that got increased) although the result was already reported.

                  Can you send me a PM about the host setup? I'm most interested in the client_state.xml but would also like to have the result files.

                    Hi Christian,
                    I'm about to head out for work, so I'll send you the files and logs later.
                    One thing, this host is a virtual machine (Linux guest on Windows host). Might be a convenient explanation, but I did not restore a snapshot and upload/report a task twice, the machine has only been started and shut down in a normal way for weeks.
                    Maybe this is a bad batch? The earlier mentioned task without deadline had an almost "identical" timestamp (exactly 2 hours apart, same minute, not sure which time zone in each case...).

                      HI think i may have a host here with a similar issue.

                      I cannot see the task i am trying to upload in its task list, which is odd.

                      I suspect task may have expired and past the deadline, although the task properties say 6 March - as the host is not often powered on it's arriving getting later than usual.

                        This is getting more and more weird. For everyone else seeing those transient upload errors I would like to know the file this is happening on and the hostid of the host this is happening on.
