<h3>Description</h3>

<p>I tested kamailio's topoh+topos modules. udp worker's private memory is leaking when i enable both.<br>
after a couple of hour kamailio stops and spams error messages.</p>
<h3>Troubleshooting</h3>
<p>kamcmd pkg.stats shows lots of real_used memory(only udp workers are leaking).</p>
<h4>Reproduction</h4>
<p>Enable both modules.</p>
