  There are many leases. Most of the errors came from "binding state backup".
  I think more than 100 clients.

  The time is sync, we are using NTP.
   
  Thank you very much for your help.

  Impossible to tell if there's a problem with your configuration file,
if we can't see it.

First step would be to try upgrading to the latest stable version
(3.0.4) which has lots of failover fixes in it.

Do you have only a few of these leases or many of them? How many
clients and how many of these leases.

What error messages, if any, are you getting?

Is the time synchronised between your dhcp servers. NTP is recommended,
but even using rdate in a cron job would be better than nothing.
