I Hope it helps, because it is quite specific.
I use a shared folder on two different macs and sometimes it happens that I forget an Emacs.app session opened on one of them. This stuck iCloud. Possibly, one Emacs.app temporary filenames is incompatible with iCloud. When Emacs.app closes the file, the iCloud sync restarts.
