Hi,
I have come accross an issue whereby when I replicate registration information to client nodes on the dmq bus, the AOR's of the client nodes for that replication event are garbled.
I am running the release version of kamailio v4.3.0 with the following 3 patches applied:
https://github.com/kamailio/kamailio/commit/894796f6f1fa2d2778ace5c56f58d204ea06efc2.patch
https://github.com/kamailio/kamailio/commit/039231a3b61c00fe36e868417144daa9f04936ba.patch

Here is a sipgrep trace of the messaging of the UAC registering and the corresponding KDMQ messages sent to the 2 client nodes on the DMQ bus:

My dmq related parameter settings are as follows:
# grep -i dmq module_definitions.cfg
loadmodule "dmq.so"
loadmodule "dmq_usrloc.so"
# ----- dmq params -----
modparam("dmq", "server_address", DMQ_ADDRESS)
modparam("dmq", "notification_address", "sip:sip-registrars:5060")
modparam("dmq", "multi_notify", 1)
modparam("dmq", "num_workers", 4)
# ----- dmq_usrloc params -----
modparam("dmq_usrloc", "enable", 1)
The "sip-registrars" host/domain name resolves to the following 3 addresses (via DNS):
10.6.0.173
10.6.0.174
10.6.0.175
I am getting the following nathelper errors in the logs of the client nodes too, I presume, because of the garbeld AOR:
