That's NFS-server related.  Used by the id mapper, I think.  On RedHat at least, I think that's started/stopped by /etc/init.d/nfslock. (Though my memory is a little sketchy on that point.)  The pipefs could possibly be mounted even if nothing's using it, also.  Got any NFS-related services running?

Afaik, an NFS server shouldn't get stale file handles.  That's a client's problem.

RedHat/Fedora:
  $ rpm -qa | grep nfs
Debian/Ubuntu:
  $ dpkg --list | grep nfs
Both:
  $ ls /etc/init.d | grep nfs
