I seem to be having some issues with queueing uploaded files this morning (CET). Uploaded files sometimes enter the queue quickly and others take forever. Reentering the jobs that havent queued works occasionally, but then not always. Jobs that do eventually start are random in the list with no positional correlation (not that I always expect this). The question is, do I wait it out or keep trying to enter them for queueing again ?
I'm not sure about your precise problem - but I'd leave the jobs in the queue just in case the queue is really long for whatever reason. You don't want to lose your place if your files are still in the queue. But I'd also create a new history and re-upload the files in that, just to see if maybe they go through. It does sometimes work.
