Lease imbalance problem

[MaryAnn Bulhoes]

Hello,
   Since upgrading to 3.1.0a1 the message logs have been filling up on
both DNS servers with lease misbalance errors like the following:

Oct 26 10:36:18 dns1 dhcpd: pool 895a0b8 10.101.5/24  total 51  free 27
 backup 20  lts 3
Oct 26 10:36:18 dns1 dhcpd: pool 895a0b8 10.101.5/24: lts <=
max-lease-misbalance (7), pool rebalance event skipped.

My message logs are huge any help would be greatly appreciated.
Thanks,
