Sorry, but I cannot do much over the weekend. Both the machine with leakage and the one without are in production (and about 40km apart from each other and away from my home :-). I still wonder if there are more circumstances needed to provoke this problem. I really doubt that this would have gone unnoticed for weeks or even months if it only takes some nfs-server serving from zfs storage and some client to see it. What does the client in your test setup look like? cu Gerrit
