My A/UX does this too. We have two machines connected to each other via
thin ethernet, and one is an NFS server with the other using one of its
disks. When I shutdown a machine, it spends an awful long time sitting
there and occasionally rattling its disk. The other machine also rattles
its disk at the same time.

It eventually does what it wants, but then it gets kill process errors.
IE, kill: PID 67 - no such process. The PID tends to be a number > 60 and
< 80, and there are usually four such messages (each PID reported is unique).

All of this appears to be of no consequence as nothing is damaged and shutdown
otherwise completes its job normally.

Any ideas?
