I have a kamailio cluster with two nodes

kamailio-1.local:  10.101.2.119

kamailio-2.local: 10.101.2.247

with dmq configs:

kamailio-1:

modparam("dmq", "server_address", "sip:MY_IP4_ADDR:5060")
modparam("dmq", "notification_address", "kamailio-2.local:5060")

kamailio-2:

host: 10.101.2.247
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 0
}
{
host: kamailio-1.local
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 0
}
{
host: kamailio-2.local
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 0
}
{
host: 10.101.2.119
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 1
}

and  kamailio-2.local show me:

{
host: kamailio-2.local
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 0
}
{
host: 10.101.2.119
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 0
}
{
host: kamailio-1.local
port: 5060
resolved_ip: 10.101.2.119
status: active
last_notification: 0
local: 0
}
{
host: 10.101.2.247
port: 5060
resolved_ip: 10.101.2.247
status: active
last_notification: 0
local: 1
}

So there are only two hosts in the cluster, but there are 4 records in dmq.list_nodes. Also in sip trace I can see that kamailio send DMQ messages to itself too (because it ip marked as local: 0 I think).

Is it ok? Is it normal behavior? What should I do to fix it? Should multi_notify and DNS name with 2 A records fix it (and why?)?
