The pipefs could possibly be mounted even if nothing's using it, also. Got any NFS-related services running?

Then you have no idea if the problem will recur or not. (If it happened once, it probably will again.) Did you ever check if you have automount running?
Take a look for automount's config files and see if anything seems familiar.
$ ls /etc/auto*
$ cat /etc/auto.master
