That is small amount in your case.

Please update systemd unit file and set

LimitNOFILE=999999

Then "systemctl daemon-reload" and "systemctl restart kamailio".
After check process limits and errors in kamailio log.

Thanks Sergey,

Didn't I?

Kamailio processes:

root 31085 1 0 11:21 ? 00:00:00 /usr/sbin/kamailio -m 1024 -M 256 -x fm -X fm -P /var/run/kamailio/kamailio.pid -f /etc/kamailio/kamailio_gsm.cfg

and the process id's limits:

Please make one

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.

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
