Hi misc@,
after upgrading our pair of dhcpd servers to 5.6(-stable), i am seeing
strange DHCPACKs in our logs (in both of them):
Nov 7 09:28:34 dhcpd2 dhcpd[9269]: DHCPINFORM from 192.168.20.251
Nov 7 09:28:34 dhcpd2 dhcpd[9269]: DHCPACK on <null address> to
5c:51:4f:56:81:c3 via em0

Nov 7 09:28:37 dhcpd2 dhcpd[9269]: DHCPINFORM from 192.168.19.38
Nov 7 09:28:37 dhcpd2 dhcpd[9269]: DHCPACK on <null address> to
74:27:ea:e5:68:68 via em0
The entries in the leasesfile are correct and the clients are getting
the right addresses, so this seems merely a logging issue to me.
