Yea, I know, I saw that. There is nothing wrong with the file system, that is a problem with Sync. None of the machines are out of space. This has happened before (on many occasions). Right now, everything is synced, but what you pointed out is a bug in the Sync software.
I have tried doing smaller folders, but the problem is there are so many of them, that it takes me FOREVER to configure a new machine (or a rebuild), which I do all too frequently).
