That isn't supposed to happen. I just checked on a machine which has
10 minute leases and I don't see that problem or those log messages.
I'd run dhcpleased in the foreground with debug logging and collect a
couple of cycle's worth to see if that gives any clues. Saving a
packet capture might be useful too ("tcpdump -i cnmac2 -s1500 -w
/tmp/dhcp.pcap port 67 or 68").

dhcpleased doesn't support this yet though it would certainly be a
feature that's useful to have.
