But it looks more like a bug in mountd, since it shows up only is snapshots are created with mount. If snapshots are created with mksnap_ffs this does not seem to show up. I still have to make more in depth experiments, but before experimenting by myself I'd like to have some more informed directions on what to experiment. -- Guido Falsi
