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.

Regards.

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?

Jurijs
