Peer rebalancing problems

I've seen references to this in previous posts, but no clear
resolution. I've got two RHEL6 boxes (dhcp-4.1.1-63.P1.el6_10) setup
in a failover pair. I discovered this morning that one server was
stuck in "communications-interrupted" state. Turns out there were two
dhcpd processes running simultaneously. Not sure how that happened,
but shockingly, it wasn't happy.

I've restarted both servers, we're back in normal failover state. But
one of my subnets is still not balancing out:

landlord01: balancing pool 55814b7e0ad0 WIRELESS-FACSTAFF  total 2970
free 58  backup 320  lts -131  max-own (+/-)38
landlord01: balanced pool 55814b7e0ad0 WIRELESS-FACSTAFF  total 2970
free 58  backup 320  lts -131  max-misbal 57
landlord02: balancing pool 55d8e05a4aa0 WIRELESS-FACSTAFF  total 2970
free 353  backup 0  lts -176  max-own (+/-)35  (requesting peer
rebalance!)
landlord02: balanced pool 55d8e05a4aa0 WIRELESS-FACSTAFF  total 2970
free 353  backup 0  lts -176  max-misbal 53

It seems a little strange that both servers have a negative LTS value.
And that they're so different. Is this explainable somehow?

Thanks,

Norman
