I'm using DMQ in order to share :
- htable
- usrloc
for usrloc seems everything working as expected.
on htable I have noticed, after some stresstest made with sipp (25 cps / 600 concurrent calls) that one of the nodes (or sometimes both) eat a lot of cpu (300%) after stresstest ended [all processes idle except f4 dmq handlers]; I tried also to change some parameters on dmq module like worker_usleep with no changes at all.
Hello Paolo,
just commenting on the first issue:
So I understood you correctly, after the stress-test you observe a not ending CPU load on the Kamailio server, even without load?
Maybe you can have a look on the CPU consuming processes by attaching e.g. "strace" to them at the next occasion, to see what they are doing.
Best regards,
Henning
At last, using kamailio in a kubernetes system I have several kamailio instances that pops-up and then tiers down with different ips; for this reason dmq seems not able to delete peers, adding, for every defunct node a warning like this : router-3 17(34) ERROR: dmq [notification_peer.c:599]: notification_resp_callback_f(): deleting server sip:172.28.1.211:5062;status=active because of failed request router-1 router-sr 17(33) ERROR: dmq [notification_peer.c:599]: notification_resp_callback_f(): deleting server sip:172.28.1.213:5062;status=active because of failed request

I think the realistic answer is that it's getting to be that way. I think DMQ is now the recommended way to share usrloc and htable across multiple hosts. DMQ+dialog is still a work in progress. Not sure about DMQ+some other new stuff.

Before DMQ there were other ways to do similar things. Is DMQ now considered the best way? Assuming I am using recent stable?
Are there any good guides on clustering Kamailio? I am not finding a lot of good info on that subject. Specifically, for multi datacenter active active where things like floating IP's and keepalived are not really an option.
