    Sending a SIGHUP to xinetd doesn't kill it and restart it. xinetd
    specifically traps SIGHUP. When it receives the signal, it rereads
    its config file, drops connections to services that are no longer
    enabled, verifies that existing connections are OK based on any new
    access restrictions, and drops arbitrary connections to match limits
    on a given service. The same old xinetd is running, but with a new
    configuration.

    xinetd logs via syslogd to the /var/log/messages file. If you examine
    that file, you'll see xinetd telling you what is going on.
