Hi Kraishak
What settings do you have in the failover peer statement on the two
servers? Can you paste the whole statement into the email please?
There is a discussion of the relevant settings in the dhcpd.conf man
page, look for the section "The Failover pool balance statements".
Perhaps if you have non-default settings for those values mentioned it
may skew the algorithm. Usually the defaults are a pretty good option,
and only change them if there is a specific problem.
regards,
