You made quite a leap going from 5.2 to 5.4 and you picked up a lot of new functionality. The z/VM 5.4 TCP/IP Messages and Codes book includes change bars for those DTCARPxxxx messages. It's telling you that you've got another host on your LAN that is configured with the same IP address as VM TCP/IP. It didn't used to warn you; now it does.
