- ------------------------------------------------------------------------
   A. Background
      A server that uses the 'swait' state in the /etc/inetd.conf file
      can be made to interfere with one or more services started by
      inetd.  This affects only installations where configuration
      alterations have been done to include 'swait' service entries.
      The standard configuration of the Internet Services product,
      InternetSrvcs, provided by Hewlett-Packard, including telnetd,
      ftpd, rlogind, etc., will not exhibit the behavior in question.

B. Recommended solution
      The problem can be rectified by installing one of the following
      patches. PHNE_20747 for HP-UX release 10.20; or
               PHNE_21699 for VVOS release  10.24; or
               PHNE_21835 for HP-UX release 11.00; or
               PHNE_23068 for HP-UX release 11.04.
