Just follow up on the progress and resolution to my stuck zones problem. I had two zones stuck in the shutting_down state.
Based on initial feedback I looked for nfs mounts in /etc/mnttab in the gz that were mounted in the ngz. There were a couple and umount'ed them. Then I was able to find two processes that indicated they were accessing the ngz filesystem, zsched and svc.configd. I tried trussing svc.configd but was unable to due to "unanticipated system error". I killed svc.configd, ran the zoneadm halt and the zone successfully shut down. On the second zone that's stuck I umount'ed the nfs file systems and checked for processes accessing the ngz filesystem and the only one reported is zsched. Trying to halt the zone doesn't do anything and from the looks of it zsched appears to be unkillable. It looks like this zone is here to stay until I can reboot the box.
