Hello,
I am setting up a Kea server in a load balancing HA configuration. I am
experiencing an issue where I am getting the error:
"HA_BUFFER4_RECEIVE_NOT_FOR_US: dropping query to be processed by another
server"
Here is an exact line from my Kea HA hooks log:
"2025-03-20 16:45:28.365 DEBUG [kea-dhcp4.ha-hooks/64143.140171193816768]
HA_BUFFER4_RECEIVE_NOT_FOR_US [hwtype=1 00:50:56:bb:e1:9c], cid=[no info],
tid=0xffbd0305: dropping query to be processed by another server"
Here is my HA configuration:
{
"library": "/usr/lib/x86_64-linux-gnu/kea/hooks/libdhcp_ha.so",
"parameters": {
"high-availability": [{
"this-server-name": "server1",
"mode": "load-balancing",
"heartbeat-delay": 10000,
"max-response-delay": 60000,
"max-ack-delay": 5000,
"max-unacked-clients": 3,
"max-rejected-lease-updates": 10,
"delayed-updates-limit": 100,
"peers": [{
//BEGIN server1
"name": "server1",
"url": "http://172.16.120.3:8000/";,
"role": "primary",
"auto-failover": true
//END
}, {
//BEGIN server2
"name": "server2",
"url": "http://172.16.120.4:8000/";,
"role": "secondary",
"auto-failover": true
//END
}, {
//BEGIN server3
"name": "server3",
"url": "http://172.16.120.5:8000/";,
"role": "backup",
"auto-failover": false
//END
}]
}]
}
All servers have the same configuration, other than "this-server-name".
