I don't see this problem yet, BUT, I've got a Sun E-450 running Solaris 2.6 that justs drives knfsd nuts. I get nfsd's that are constantly running, and without the NFSv3 in mountd disabled (which is already fixed), Solaris can't mount the volume.
Kernel is 2.1.122, knfsd980920, both patches applied.
I'm looking for more information on what to do to figure out what makes those
