<p>Daniel,</p>
<p>Thanks for the tip, recompiled and got a new trace</p>
<p><a class="moz-txt-link-freetext" href="https://pastebin.com/NxCXA1gT">https://pastebin.com/NxCXA1gT</a></p>
<p>Not sure what happened, but sometimes running kamctl trap
restores Kamailio functionality to accept connections.<br>
</p>
<p>Thanks in advance!<br>

<p>is libssl/libcrypto compiled/installed with debugging symbols?
They are not shown in the backtrace.</p>

<div>I'm continuing investigations on Kamailio and stress
test. Got it again in the state where it's not accepting any
new TCP/TLS connections (UDP still works though), but all
looks good from lsof/netnstat part, like system is not
reporting any zombie connections. Restart of Kamailio
process helps<br>
