I’m experiencing some sync problems with indexed files.
In the log, I receive the “…items left to be uploaded” message. When I search “item:pending”, the items are listed as not yet downloaded (“File not yet available” in the DT window), but the files are on my HD in Finder when I go to their locations (right-click, Reveal in Finder).
They’re indexed in a DT database of bibliographic, reference material. The actual files are in a location for another program (Zotero, a citation/reference manager). Zotero syncs those files and they’re accessible by my other machines. This uploading/pending issue is a recent occurrence.
If not, I would disable Zotero’s syncing and see how it behaves. Bear in mind, syncing things that are syncing things is adding complexity to the environment.
Turning off the Zotero sync hasn’t made a difference with the pending items. That wasn’t an issue until Zotero’s recent update, so that may be where the problem lies.
