Probable bug found on HP-UX

I'm setting up a dynamic DNS/DHCP server on HP-UX 11iV3 (11.31).   I have bind 9.7.3 up and running without issue.
However I'm having issues with dhcp.  This is version 4.2.4-P2

This machine only has one NIC called lan0 (the others are just un-configured link aggregates).

[root at kinnauga ~]# ifconfig lan0
lan0: flags=2000000000001843<UP,BROADCAST,RUNNING,MULTICAST,CKO,TSO>

When I start the server I get:

Now to my eyes, the dhcpd is indeed configured with a subnet declaration for the subnet it is on so I cant understand why this is happening.   I'm starting to think that the "(no IPv4 addresses)" part of the error message seems to indicate that the dhcp server is unable to determine the IP address on the NIC?

Any help is appreciated :)
