Hi Charles,
Yes I exit after the handle_dmq function in the request route.
I couldn't spot the looping this time (as it is intermittent), but here is the
trace of messages that may indicate something weird or unexpected happening
with DMQ:
The following message came from Node B to A (which should never have originated
because only A is receiving calls). I am assuming KDMQ will only flow from A
--> B followed by their acks from B.

Hi Pat,
In your config, do you exit immediately after handle_dmq_message()?
Are you able to share with us one of the looped messages, both as it is
received by B and then as it is sent back to A?

Hi,
I am using Kamailio 5.1.1 with DMQ with the following config (relevant parts)
on 2 nodes.
Node A:
modparam("dialog", "enable_dmq", 1)
modparam("dmq", "server_address", "sip:no.de.a.ip:5060")
modparam("dmq", "notification_address", "sip:myvoip.local")
modparam("dmq", "multi_notify", 1)
Node B:
modparam("dialog", "enable_dmq", 1)
modparam("dmq", "server_address", "sip:no.de.b.ip:5060")
modparam("dmq", "notification_address", "sip:myvoip.local")
modparam("dmq", "multi_notify", 1)
"myvoip.local" is a DNS A record that resolves to both the IPs of A and B.
I have the dmq_handle_message(); called if method is of type "KDMQ" in the
request_route.
Now, in order to test it, I only sent a few calls only on node A.
KDMQ messages flowed to node B and dialog state replicated. But I noticed, node
B was randomly sending one of the KDMQ dialog messages back to A and receiving
a 500 "Server Internal Error" back from node A... (for a subset of those calls,
not all).
Why would this be the case when the nodes correctly recognize their local
status by the "local: 1" set as seen from dmq.list_nodes
Anyone else experienced this? What could I be doing wrong?
Thanks,
Pat.
