[K12OSN] DHCP gone wild

[Jack]

Had to reboot server again last night.  Thats twice in one day. 
CPU usage right now is about nil as well and DHCP is using almost
nothing.  However when I reset the server last night I never reset the
terminals.  As a result my messages logs look normal and have normal
DHCP logs.  I am resetting both terminals now.  I'll take the readings
later in a few hours.
