We don't have a periodic execution mode for SMF like Oracle Solaris.
The NFS cleanup task is run from the default root crontab:

    http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/Adm/root?r=fd324b96#30

I'm not sure exactly but it seems like nfsfind is a pretty basic shell
script that may not have both its arms completely around the problem.
It'd be good to get an illumos bug logged with the issue you've
described, including the sequence of ZFS/NFS operations you've used to
get the system into this state so that whatever the fix is can be
tested well.

Cheers.
