<p>Not sure what happened, but sometimes running kamctl trap
restores Kamailio functionality to accept connections.<br>

<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>
