I think you mean, "when the client REQUESTed the lease",
as the ACK is from the server.
I'm seeing this on some of our networks too. So far, it seems
not to be hurting, so we've not begun to treat it as "urgent".
It is on my list for attention quite soon.
I have no hard information yet, but I suspect rogue clients with
manually configured addresses interfering with the well-behaved.
In more detail, but without having thought too much about it,
I guess what's happening is the following.
[ server can't see address in use,
as we block ICMP to a (too) large extent ]
client checks for address in use
It may be that my brain is on another planet. 8-)
