Hello, what is the kamailio version? Were these bare tcp or also tls connections? Stretch comes with libssl 1.1 which is a major refactoring and wondering if that can be an effect. Did you have to restart or the connections were ended after a while? Being just a temporary pike ... What is the tcp connection lifetime value you use? Might help a bit, you can increase the number of max tcp connections in kamailio (default is 2024). - https://www.kamailio.org/wiki/cookbooks/5.0.x/core#tcp_max_connections Cheers, Daniel On 28.09.17 07:51, Jurijs Ivolga wrote:

Hi Guys, I recently tried to use Debian Stretch in production and it didn't went well. On load(500k-700k SIP messages per day) I get a problem that at some point there was a pike of CLOSE_WAIT connections(up to 2k of CLOSE_WAIT connections) and no new connections was possible, I tried to figure out where problem is, but I didn't found anything in system or Kamailio logs, Kamailio just stopped to receive traffic via TCP, but UDP continued to work. Test environment where was no load I didn't faced such issue. Just curious is there anybody who are using Debian Stretch in production without issues?

Try adjust LimitNOFILE on systemd <https://www.freedesktop.org/software/systemd/man/systemd.exec.html> unit If this will help then create ticker and i will create PR Example <https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/debian/freeswitch-systemd.freeswitch.service> чт, 28 сент. 2017 г. в 8:51, Jurijs Ivolga <jurijs.ivolga(a)gmail.com>om>:

Hi Jurijs, You have also DefaultLimitNOFILE in systemd that could be different of the values you see in console: https://www.freedesktop.org/software/systemd/man/systemd-system.conf.html You should test to put LimitNOFILE in systemd unit file, just to be sure. BTW, we had also some strange behaviors with TCP, Kamailio 5.0 and Debian Stretch. But with the Kamailio 4.4 integrated in Debian repository, it seems OK for now.

I had a similar problem and had to recompile Kamailio linked to openssl 1.0.X in debian stretch, since then, 0 issues with Tcp&ssl. I know Daniel did some changes so you might want to try out latest 5.0.3? I don't know if his patches got backported to 4.X... This is the issue I had: https://github.com/kamailio/kamailio/issues/1172 Not the same cause, but also related to openssl 1.1: https://github.com/kamailio/kamailio/issues/1189 Joel.

Hi, Ok, I'll confess, I'm running Kamailio in docker and with root user, so limits should be fine... With kind regards, Jurijs On Thu, Sep 28, 2017 at 2:54 PM, Ludovic Gasc <gmludo(a)gmail.com> wrote:
