ISC dhcpd failover question

I have a question regarding failover in dhcpd. Running 3.1.1 on rhel3
linux. I've been staring at the documentation for awhile - and I'm
just not seeing the answer.
We have a fleet of remote sites. Each site looks like this in terms of dhcpd:
server A(primary) and server B(secondary)
Say server B drops off the face of the planet. Server A continues
handing out addresses in 'communications-interrupted' mode. But
eventually it exhausts it's leases - and starts spewing "peer holds
all free leases".
So, is there anything in there that causes the primary to give up on
the secondary eventually - and start pillaging its leases? Or do I
need to handle that condition with some external logic?
