Hi 
I have stopped both the dhcpd.services on the primary and failover and
started one after the other, now it is working fine but just want to sure
what would be the reason of not giving the lease at that time
These are logs at that time 
Oct 25 12:47:51 server1 dhcpd[11541]: *failover: link startup timeout*
Oct 25 12:47:51 server1 dhcpd[11541]: DHCPDISCOVER from a3:4c:12:b6:d0:1e
via xxx.xx.xx.x: peer holds all free leases
Oct 25 12:47:51 server1 dhcpd[11541]: DHCPDISCOVER from 6d:8b:d4:aa:9b:9a
via xxx.xx.xx.x: peer holds all free leases

The above contents are from the previous lease files which i have, Currently
both are in normal, normal state for both
