Question about DHCP.

[Eric Kenny]

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.
