Could you do a file search to find files which have been modified within the day that the unused space was erased and of whom the file size is unreasonably large? I remember such a bug in v5 a long time ago... though no one's fixed it since it was unreproducible and v5 is frankly old.
If you can't find a solution, I'm afraid I'm out of ideas too.
