I'm pretty sure the best hint is the information that you have from the
message above, as cryptic as that is.

That will only list processes that are in the zone. There may be global
zone processes that have a hold on something in there too. This should
tell you about them:
# grep $uuid/ /etc/mnttab | nawk '{print "fuser -c", $2}' | sh -x
The resulting "fuser /zones/$uuid" could turn up some false positives of
processes that have holds outside of /zones/$uuid/root.

After killing any processes that the command above gave, you can also try
unmounting any file systems that are still in the zone.
# grep $uuid/root/ /etc/mnttab | nawk '{print "umount", $2}' | sort -r | sh
-x
Follow that up with a 'zoneadm -z $uuid halt'.
That may or may not work for you. If it doesn't, I think you will need to
take a reboot. I'm not aware of the history in this area since the Oracle
closed down OpenSolaris. Those that have been on the outside all these
years may know of other developments in this area that can be helpful.
