Hi Björn, ok – if they are having unique call-ids, then it will probably not work. I did not had a test environment right now available to check. Maybe this would be an approach to fix it somehow for the dialog module, by switching to one call-id per actual dialog.

But in my understanding, this paramater just helps ordering the packets within the same callid. I'll report back as soon as I'm done with testing. With best regards, Björn Am 19.09.25 um 15:41 schrieb Henning Westerholt: Hello Björn, right now, this is not possible to configure, you are right. The DMQ workers are shared and just processing all the different messages for it randomly depending on the Linux scheduler. So, it can happen, as you observed, that the order of some messages is not correct. Thinking about it, the better modification might be to somehow order the requests before they are processed from the DMQ workers. I am not sure if it will help, but worth a try nevertheless – please set this option: https://www.kamailio.org/wikidocs/cookbooks/5.8.x/core/#route_locks_size See if it maybe helps with the message ordering also in the DMQ case.

We also use DMQ in production for replicating usrloc, htable and dialog. So far so good. But in my log I regularly see the following message: ERROR: dialog [dlg_dmq.c:293]: dlg_dmq_handle_msg(): dialog [22051:221142] not found As I tried to troubleshoot this message I discovered the following: On network everything is OK. The KDMQ messages are sent and received in the correct order. But they are not processed by the DMQ system in Kamailio in the correct order. It might happen that the dialog KDMQ message for the initial INVITE is not processed before the KDMQ message for the provisional response. I repeated the tests in my lab with different number of workers for DMQ. But after I set the number of workers to 1 everything seems to be fine. But now comes the problem. As I mentioned, we also replicate htable between the nodes, so we can use all nodes as hot standby. If I raise the CPS one worker is not enough to handle htable and dialog and userloc. So I thought it might be cool to have the possibility to set the amount of worker for the modules separately. So I would just use one worker for dialog and all other workers for any other modules that use DMQ because in my opinion dialog is the only thing where the order of the KDQM messages matters. As I'm not capable of programming things like that I wanted just put this a think for further developments of DMQ. I'm really looking forward to your thoughts about this.
