<p>Hello,</p>
<p>what is the kamailio version?</p>
<p>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.</p>
<p>Did you have to restart or the connections were ended after a
while? Being just a temporary pike ...<br>
</p>
<p>What is the tcp connection lifetime value you use?<br>
</p>
<p>Might help a bit, you can increase the number of max tcp
connections in kamailio (default is 2024).</p>

<div>Hi Guys,<br>
<br>
</div>
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.<br>
<div>
<div><br>
</div>
<div>Just curious is there anybody who are using Debian
Stretch in production without issues?<br>
