maybe the files you removed are still open by some other process?
info unlink
      The `unlink' function deletes the file name FILENAME.  If this is
      a file's sole name, the file itself is also deleted.  (Actually,
      if any process has the file open when this happens, deletion is
      postponed until all processes have closed the file.)

use lsof to find processes which might still have the file open.
