Thanks, Darren, The main issue I face is 1. I have created a scope 3.0.0.10 - 3.0.0.20 2. I have generated leases from that scope. 3. I deleted that scope and created another one in the same subnet 3.0.0.50 - 3.0.0.100. 4. When I fetch the active lease, I am also getting the leases from the deleted scope 3.0.0.10 - 3.0.0.20 also ( I shouldn't get them right?). How do I solve this? I tried the LFC process, which only cleans up the leases from the lease file, but the memory still has them. Here is my config file. {"Dhcp4": { "interfaces-config": {"interfaces": ["eth0"]}, "authoritative": true, "multi-threading": { "packet-queue-size": 16, "enable-multi-threading": true, "thread-pool-size": 4 }, "loggers": [{ "debuglevel": 55, "severity": "DEBUG", "output_options": [{ "output": "/var/log/kea-dhcp4.log", "flush": true, "maxsize": 204800 }], "name": "kea-dhcp4" }], "lease-database": { "name": "/opt/dhcp/dhcp/db/dhcp4.leases", "persist": true, "type": "memfile", "lfc-interval":60, }, "hooks-libraries": [{"library": "/opt/dhcp/lib/kea/hooks/libdhcp_lease_cmds.so"}], "server-hostname": "server-47", "control-socket": { "socket-type": "unix", "socket-name": "/opt/dhcp/dhcp/kea4-ctrl-socket" }, "decline-probation-period": 7200, "sanity-checks": {"lease-checks": "fix-del"}, "subnet4": [{ "subnet": "3.0.0.0/8", "valid-lifetime": 86400, "option-data": [ { "data": "www.shobhith.com", "name": "domain-name" }, { "data": "86400", "name": "dhcp-lease-time" }, { "data": "255.0.0.0", "name": "subnet-mask" }, { "data": "3.0.0.1", "name": "routers" } ], "pools": [{ "client-class": "allow-client", "pool": "3.0.0.50-3.0.0.100" }], "id": 818110 }], "client-classes": [ {"name": "deny-client"}, { "test": "(not(member('deny-client')))", "name": "allow-client" } ] }} Thank you.
