ISC dhcpserver will assign an infinit leasetime for a bootp request
You can use a global statement :
dynamic-bootp-lease-length 86400;
to limit these leases ( to 1 day in the above example)
Have a look in dhcpd.leases and confirm the infinit leases !

Sorry about my e-mail address, but i'm trying to keep spam out.
Remove "icke-reklam" and it works.
