It just happened again on one of my slaves just after an update and the last thing it said was:

Jan  7 10:56:13 slave dhcpd: [ID 702911] DHCPREQUEST for aaa.bbb.66.156 from 00:14:38:8b:00:8f via e1000g2: lease unavailable.
Jan  7 10:56:13 slave dhcpd: [ID 702911] DHCPNAK on aaa.bbb.66.156 to 00:14:38:8b:00:8f via e1000g2

That IP is in the dynamic range which starts at 66.100 upto 66.220. This is a new building and staff are in the process of moving in..
