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).

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?
