Hi David, 

Are you sure you refresh systemctl daemon reload after edit? 

Centos 7.7 works with that (the capability setting is only needed if user Kamailio runs for example port below 1024 like 443). 

cat /etc/systemd/system/kamailio.service.d/override.conf                                         
# Generated by puppet                                [Service]
LimitNPROC=100000                                    LimitNOFILE=100000
AmbientCapabilities=CAP_NET_BIND_SERVICE

You can check that setting after 
systemctl daemon reload 
systemctl restart kamailio

In the proc filesystem for example one pid is 16420

cat /proc/16420/limits

Cheers 
Karsten

Try without the two [Service] sections... not sure if that can be the problem. 

Move the LimitNOFILE=65536 to the existing section where the test of params are. 

Then daemon-reload and retry...

Maybe it works.

Hello guys,

I tried that and it _seems_ to be working, BUT:

running `service kamailio start` just stays there and fails after about a minute:

Job for kamailio.service failed. See 'systemctl status kamailio.service' and 'journalctl -xn' for details.

running systemctl status kamailio.service replies with:

Is it possible systemd is taking those "ERROR"s as an indication the service is not starting properly? Even though it is?

my service unit file is like so:

~# cat /etc/systemd/system/multi-user.target.wants/kamailio.service

Depends on what init system you use. If you have to ask I pesume you are
using systemd (since they like to reinvent the wheel). The correct way
is to:
systemctl edit kamailio.service
and add:
[Service]
LimitNOFILE=65536

More quick and dirty:
edit /etc/systemd/system/kamailio.service.d/override.conf
and insert the same as above. And do a
systemctl daemon-reload
