Re: [SR-Users] tcp limit, too many open files

29 Nov 2019

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

 Do you know how to set it? First time doing thousands of tcp  registrations..

 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
