I gather warhol-00 is running 7.1-S+ZFS.
How recent a 'stable' is it?
Where does ZFS fit in?  Is sunfire:/dist mountpoint in a local ZFS or
is a local ZFS mountpoint inside the sunfire:/dist mount?
Do you get the same problems without any ZFS mounts?
Is this a TCP or UDP NFS mount?  What happens if you switch protocols?
What NIC are you using and are you seeing any network errors?
Are you able to capture a protocol trace showing the transaction including
erroneous packet?
