The above seems to be a meaningless statement.

DHCP (and its expectations) are not very complicated.

I use the ISC DHCP server here, but any reasonable DHCP server should 
do.

The DHCP client is expected to contact the server every so often and 
if the server fails to respond for a very long time, the DHCP lease 
will expire and the DHCP client should remove the IP address from the 
interface.

However, it appears likely that the DHCP server and client are not the 
guilty parties here.  It appears that some other software, or 
something in the kernel, is removing the IP address.  The DHCP client 
expects the kernel to retain the IP address until the interface is 
turned down.  It is not going to continually check to verify that 
nothing has disturbed it.
