Question about DHCP.

We experienced the same behavior with our failover setup. We have
LOTS of subnet declarations (most of them /21) and found that it
would take between 1.5 and 3.5 hours for the DHCP servers to come out
of "recovering" state. As most would expect, this pretty much makes
failover useless to us.
We have been looking into other options, like using hearbeat and
direct all DHCP requests to a "service IP" instead of the actual IPs
of the DHCP servers.
If anyone has any better ideas, they would be greatly appreciated.
