Hi List
I wanted to take one of our cores down gracefully by not destroy
running dialogues to be able to implement a config change on Kamailio
5.5
For this I did:
kamctl dispatcher.remove ID SIP-URI, for every IC
This worked fine, Kamailio is instructed to reply 503 on out of
dialogue traffic from unknown endpoints causing the endpoints to
re-route traffic to the other core, eventually making it possible to
stop and restart Kamailio without harm.
dialog count was steadily decreasing, until after about 10 minutes
after removing the dispatcher URI's it started to increase again.
kamctl dispatcher.list shows me, all dispatcher URI I removed are back!
There is no ds_reload() being executed by calls.
In the module description, I find no hint, that the dispatcher config
is being reloaded from file in some interval or so.
What could be the cause of my removed dispatcher suddenly being back?
there is no automatic reload, be sure you do not have some timer routine
(inside kamailio.cfg or cron.d) that does it, or an external application
(e.g., management application).
To double-check, once you run the remove command, do a dump of in-memory
records to be sure it was removed, maybe the command fails and there
should be error messages about that.
Cheers, Daniel
