Hello !

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.

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

Any suggestion is very appreciated

Thanks!

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.
