    I suspect that the fix for bug #141773 (which is presumably a security
    issue because bugzilla won't let me see it) mentioned in the changelog
    for the updated package has introduced this problem:

    * Fri Feb 25 2005 <SteveD@RedHat.com> 2.12a-20

    - Changed nfsmount to only use reserve ports when necessary
       (bz# 141773)

    I've just observed the exact same problem with my RH9 NFS server and
    also with an HP-UX 11 server, though my RHEL3 and FC3 servers are
    unaffected.

    I suspect it might be possible to work around this by convincing
    nfsmount that using the reserved ports is "necessary" for the older
    servers, but I haven't figured out how to do this yet.

    Paul.
