[SR-Users] 5.2.3 - dispatcher module looses setid

[Karsten Horsmann]

Hi Andrew,

I said that kamctl thing cos I used it in daily basis (muscle minded) and
never saw an empty list if the target hosts are not in trouble.

But there are many moving parts.
For example I use ip addresses for my internal dispatcher configs.

As you described in the last post you are using dns names.

Kamailio had many options (and default options) to tweak and change the dns
behavior.

And you described "its in version 5.2.3".
What version did you use before?
5.0.x to 5.1.x had breaking avp changes in that module and renamed the avp
to something else (see changlogs).

Maybe some of all this moving parts change. And maybe it's an broken dns
resolver or the settings are not optimized for your needs.

As help to see why the dispatcher dump is empty some additional log
informations would be a good thing to do.

And the configuration part could be also useful.

I personally not see that described behavior with Kamailio 5.2.3 (on
Centos). And the dispatcher module is one of the most popular modules AFAIK.
