  IN IRIX 5.2, SGI's mount daemons (/usr/etc/mount_*) can fool some NFS
  clients (TGV's Multinet NFS for VMS, for one) into thinking that the
  mount daemons are NFS servers and trying to connect to them as
  such. If the client can mount filesystems from your machine when no
  mount daemons are running, but not when they are, this is your
  problem. Fix it by upgrading to IRIX 5.3 or, if you're daring,
  stealing the mount daemons from an IRIX 5.3 machine.

  Zsolt Bagoly <bagoly@ludens.elte.hu> reports that DEC OSF1 and Linux
  clients can work around this problem with the option "port=2049",
  e.g. 'mount -t nfs -o port=2049 server:/path /mount-point'.
