Error description

  • System crashes with the following stack trace when using
    automount
    with -hosts map AND when the NFS server has exported
    parent and
    sub-directories.

    AIX NFS server does _not_ allow parent and
    sub-directories to
    be exported, so this problem does not happen when using
    AIX NFS
    server.
    

Local fix

  • 1. Do not export parent and sub-directories at the same
    time.
    OR
    2. Use manual mounts instead of automount
    

Problem summary

  • host map AUTOFS may crash when NFS server has exported both
    parent and sub-directories.
    

Problem conclusion

  • Ensure directory names are properly tokenized.
