Solving POOLREQ... how?

So I have a pair of ubuntu linux 8.04 servers running DHCP 4.1.0 with a
large config (a little over 500 shared network declarations). And
everything was running great with no problems for about a month since I
first built them.
Then I added a set of about 20 networks to the config on each machine
and upon restart I start seeing this on the primary :
Jul 13 14:07:39 primary dhcpd: peer fopeer: Got POOLREQ, answering
negatively! Peer may be out of leases or database inconsistent.
and this on the secondary.
Jul 13 14:07:39 secondary dhcpd: pool response: 0 leases
As far as I can tell none of my pools are even close to being out of
addresses, the config files for the added networks are identical on both
machines. So far I haven't been able to find a config difference
between the machines that would account for this.
So I assumed it to be something in the leases file, and hoped that the
machines would re-balance themselves. I've let them run for over a
week, and except for an occasional period of time where I would see the
secondary log
pool response: 1 leases
Can anyone tell me how to interpret and/or troubleshoot this problem.
This feels oddly like a new version of the "peer holds all free leases"
problem in older version, which I was hoping to avoid by using the 4.x
train of software.
Thanks
Jeff
