New subject: registrar::save() does not save 'received' field of the 'location' table

20 Nov 2018

Hi,

We deploy kamailio in the cluster containing two nodes (Active and
Passive). When Active node becomes Passive, our websocket clients continue
sending REGISTER to this node. Passive node routes these requests to the
Active node through the UDP, that causes the following warning message:

2018-11-14T04:43:31.070005-08:00 qapbx-ca1-1 kamailio[25597]: WARNING:
<core> [core/forward.c:231]: get_send_socket2(): protocol/port
mismatch (forced udp:64.78.52.88:5060, to ws:10.9.3.116:20033)

Every registered client should be stored in the 'location':

$var(save_val) = save("location", 0, "sip:$au@$td");
if ($var(save_val) <= 0) {
xlog("L_ERR", "[$fU,R,$ci]: Registration saving failed, contact
$ct");
sl_reply_error();
} else if ($var(save_val) == 3) {
xlog("L_INFO", "[$fU,R,$ci]: Unregistration accepted. Login: $fU; ua: $ua;
s-ip: $si; s-port: $sp; 3d parm: sip:$au@$td");
} else {
xlog("L_INFO", "[$fU,R,$ci]: Registration accepted. Login: $fU; ua: $ua;
s-ip: $si; s-port: $sp; 3d parm: sip:$au@$td");
}

Log output of the Avtive node:

but in this scenario the save() method stores null value in the 'received'
row. How can I fix it?

Thank you,
