This is quite different.   The client is behaving normally.  In my case,
the server is pinging and finding that the address is in use and
"abandoning" the IP.  This is fine, but it seems that the server
"counts" the lease against the client's lease-limit.

Turns out that the abandoned IPs are actually unauthorized static
clients, so ping-check saves us from an address conflict in this case.

I've removed the offending IPs from the pool to mitigate while I deal
with the misconfigured clients.
