I'm uploading all of my photos to SmugMug via PMP. I'm basically uploading as many albums as I can do in a day and PMP keeps uploading. Did this for a 4TB year fine. A 8TB year on a different machine hit a limit, with "not enough space for upload cache" error on the next album, about half way. I let PMP run for a day without adding new albums, the hard drive free space increased from 400GB to 600GB, but I'm still getting that error trying to upload that small album. I don't see upload cache in the settings. Where do I configure it?
