Description Stefaan De Roeck (RETIRED) gentoo-dev 2009-05-04 20:49:17 UTC 
When unmounting nfs filesystems on a remote linux host, the remote system's logs show lines such as:
  mountd[2211]: refused unmount request from baobab for /usr/data (/usr/data): illegal port 51259
nfs-utils-1.1.4 does not have this problem.  It is especially annoying where automount is used to access several network drives, and logs are flooded.  

Seems to be fixed upstream in 1.1.6, see http://linux-nfs.org/pipermail/nfsv4/2009-April/010472.html:
    Turns out we do actually need to use a privileged port for UMNT.  The
    Linux rpc.mountd complains if an ephemeral source port is used:

Running on an up to date ~amd64 system.
