No, I said, I am getting an ip address, that is not in the dynamic range.
The ip address I am getting is reserved for a different host and is not
overlapping with the dynamic range.
> Now you are saying that a different host is getting a static ip.
As said, a new host is getting a static ip. But that host does have a different
mac address.

I realize that this is possible, but it won't be passed to the failover peer in
such a case. You have to use OMAPI to add it to both servers. It seems that
this lease was handed out dynamically due to the log line about difficulty
passing it to the failover peer.

I just had a thought ... is it possible that dhcpd has not been restarted since
the config file has been modified? Perhaps the running config is not the same
as that on the disk and 10.91.120.80 is still part of a dynamic range?

Yes - I am getting such messages. Not every time, but enough to be annoying.
