dhcp log snippets for this lease on the primary and secondary look
normal?

it's a backup lease, i'm pretty sure that's a safe condition for them
to be in.

both servers think the lease is in backup state.  the lease belongs
specifically to the failover secondary.

what's leading you to believe that there's a question of ownership?

other than the hardware address, i don't think any of those other
values get synchronized between servers (there are several patches
floating around that make one option or another get passed through
the failover channel).


this doesn't look healthy, anyway.  i'm guessing something along the
lines where the failover state changed to communications-interrupted,
the backup lease was allocated to someone (moved to active), and then
expired and went back to backup state.

or any sequence of events in which the state change from backup to
active wasn't received or processed by the primary.
