dhcpd.leases file missing old lease IP after each dhcpd restart

[P N Kumar]

Hi All,

Please help me on this issue which I have been working since long time.
We use ISC DHCP 4.2.8 server to assign fixed IP address to clients.

On the first config commit server leased out 6 IP address to 6 clients.
4.4.4.1  to  4.4.4.6

When I restart 1st time  ,DHCP "/etc/init.d/dhcp-server restart", I can see
all 6 leases exist in dhcpd.lease file


2nd time restart misses first lease IP i.e. lease file has  4.4.4.2-4.4.4.6
3rd time restart  lease file has  4.4.4.3-4.4.4.6
...
...
5th time restart  lease file has  4.4.4.5-4.4.4.6
6th time restart  lease file has  4.4.4.6

but I can still ping 4.4.4.1 (or any other missing IP) from DHCP server.

Has anyone seen this behavior?

Thanks for your help in advance.
