Hi Robert, <br>
<br>
Thanks for the suggestion, however, I already have that module
parameter enabled as described in the original post <span
class="moz-smiley-s1"><span> :-) </span></span>:<br>
<br>
modparam("dmq", "server_address", DMQ_ADDRESS)
<br>
modparam("dmq", "notification_address", "sip:lb.domain.com:5060")
<br>
<b>modparam("dmq", "multi_notify", 1)
</b><br>
modparam("dmq", "num_workers", 4)
<br>
<br>
Thanks<br>
<br>

All,<br>
<br>
I have an issue with the dmq_is_from_node() function,
whereby it does not detect a node is on the bus if it
has been removed from its "table" due to previously
failed, i presume, ping requests.<br>
<br>
I have the following snippet in my main routing block:<br>
<br>
if(is_method("KDMQ")) {<br>
if (dmq_is_from_node()) {<br>
dmq_handle_message();<br>
exit;<br>
} else {<br>
xlog("L_INFO", "KDMQ message recieved from
node not on our bus!! ($si:$sp) Dropping.");<br>
exit;<br>
}<br>
}<br>
<br>
I have the following dmq module parameters enabled for
dmq:<br>
<br>
modparam("dmq", "server_address", DMQ_ADDRESS)<br>
modparam("dmq", "notification_address", "sip:<a
moz-do-not-send="true"
href="http://lb.domain.com:5060" target="_blank"
rel="noreferrer">lb.domain.com:5060</a>")<br>
modparam("dmq", "multi_notify", 1)<br>
modparam("dmq", "num_workers", 4)<br>
<br>
DMQ_ADDRESS is set to each of the addresses in the <a
moz-do-not-send="true" href="http://lb.domain.com"
target="_blank" rel="noreferrer">lb.domain.com</a>
for each local kamailio instance<br>
<br>
<a moz-do-not-send="true" href="http://lb.domain.com"
target="_blank" rel="noreferrer">lb.domain.com</a>
resolves to the following addresses:<br>
10.6.0.109<br>
10.6.0.110<br>
10.6.0.111<br>
<br>
If I start up the 1st instance of kamailio and do not
start the other 2 within the default ping timout then
I get the expected log message of dmq removing the
nodes from its table, for example:<br>
<br>
kamailio[26657]: ERROR: dmq [notification_peer.c:588]:
notification_resp_callback_f(): deleting server sip:<a
moz-do-not-send="true" href="http://10.6.0.111:5060"
target="_blank" rel="noreferrer">10.6.0.111:5060</a>
because of failed request<br>
kamailio[26657]: ERROR: dmq [notification_peer.c:588]:
notification_resp_callback_f(): deleting server sip:<a
moz-do-not-send="true" href="http://10.6.0.110:5060"
target="_blank" rel="noreferrer">10.6.0.110:5060</a>
because of failed request<br>
<br>
However, if I then start one, or both, of the other
nodes, then the KDMQ requests are dropped due to my
snippet above, I presume, because dmq_is_from_node()
checks its "active" table. See messages below as an
example of the above snippet in action:<br>
<br>
kamailio[26656]: INFO: <script>: KDMQ message
recieved from node not on our bus!! (<a
moz-do-not-send="true" href="http://10.6.0.110:5060"
target="_blank" rel="noreferrer">10.6.0.110:5060</a>)
Dropping.<br>
kamailio[26656]: INFO: <script>: KDMQ message
recieved from node not on our bus!! (<a
moz-do-not-send="true" href="http://10.6.0.111:5060"
target="_blank" rel="noreferrer">10.6.0.111:5060</a>)
Dropping.<br>
<br>
Is this expected behaviour from the dmq_is_from_node()
function? I would have expected it to always check the
addresses resolved in the notification address, or am
I using this function in a manner not intended.<br>
<br>
Any suggestions/tips would be greatly appreciated.<br>
<br>
Thanks<br>
