I have been experiencing these too. 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.
