I've been exploring this a bit. When I mount a filesystem, 2 clients get created. With NFSv4.0, the second client is immediately deleted, and the first client is deleted one grace period after the filesystem is unmounted. With NFSv4.1 and 4.2, the first client is immediately deleted, and the second client is deleted immediately after the unmount. Do you know why two clients are created? I could dig through the code ... but maybe you already know. Thanks, NeilBrown
