 Subject:  Strange DHCP problem....
 Date:  Wed, 14 Apr 2004 20:56:19 -0700
My Flash card is filling up with DHCP stuff. I only have like 15 
servers connecting to the box.  I look in the dhcpd.leases file and see 
stuff repeated over and over...  Is this normal?  It will fill the dhcp 
file until it consumes all space on the flash card.
