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
