Dropbox is stuck syncing after an update, what can I do?

FOR Anyone witrh the NEW relase that is now STUCK syncing/restarting/limbo

OK what appears is the database DB uses to monitor your files was "updated" and the process requires a reindex. For reasons unknown thios doesnt seem to work anywhere near well enough.

Here was my solution to get around it.

1) UNLINK the PC, restart

2) rename the DROPBOX folder OLDBOX

3) LINK the PC, during signup, select to selectively sync NOTHING!

4) Once upto date (with no files present), change your settings to what they used to be, like save space settings etc, and apply

5) Once upto date (should be near instant), change the selective sync to what it used to be, and apply.

6) shutdown the DB app

7) move the content of the saved folder OLDBOX over top the the current dropbox content

8) start the DB app again

9) await it to sync/check/update (takes a while but is a **bleep** load faster now)

Its STEP 5 that I think helps, when you have cloud only files I expect you get all the reindex data sent to you from the dropbox servers as you dont have the files so cant reindex them. Then when you replace those with the original files and restart the app, it sees a real file and compares the content to the index data, and finds it the same so moves on. This appears alot quicker than reindexing the original files and then comparing it to the dropbox servers index data, its likely just a timing or bulk activity thing, that you get sent all the index data at once when you change the selective sync rather than fetching it yourself form the file then comparing that to the servers one file at a time.

I just got a server with 2+TB in 700k+ of files back up. 

While it was processing a few files were updated rempotely and the syustem dealt with them as they appeared, likely on a sperate execution thread.

Hope this helps someone at least!
