Constant upload traffic after moving folder out of Dropbox and back in

[nyanpasu64]

I'm running Maestral 1.5.2, on Arch Linux, using pipx install --system-site-packages maestral[gui] a while back, and subsequent pipx upgrade-all.

1 or 2 days ago, I accidentally moved a large folder out of my Dropbox and back in. Since then, Maestral has been saturating my upload bandwidth. I think it's trying to reupload all of the files I moved. "Show Recent Changes..." shows a bunch of files uploaded a few days ago (I'm not sure if it's before or when I moved the folder), but nothing today.

maestral status says "Indexing local changes...". How should I debug this?

According to https://www.dropbox.com/deleted_files I had deleted a large number of files on 2021-11-26. I think that's around the time Maestral started uploading files nonstop, but I'm not sure because ~/.cache/maestral/maestral.log got emptied when I enabled debug logging using maestral log level DEBUG. (Protip: use maestral start -f to run Maestral as an app instead of starting a background daemon.)

In any case I restored all the files that were deleted around the same time. Now Maestral isn't uploading files anymore.

I suspect this was a Maestral bug, where Maestral continually uploaded files, and didn't stop at uploading each file once. At an upload bandwidth of around 1 megabyte/sec, and around 6 gigabytes of files deleted, that should take 6000 seconds (or 1.67 hours) to finish uploading. But I was using my computer for over a day (probably ≥12 hours of my computer being awake) and Maestral never stopped uploading. I suspect that Maestral never actually uploaded a single file successfully, since I see no conflicted files after restoring all deleted files from the Dropbox website.
