Description

I tested kamailio's topoh+topos modules. udp worker's private memory is leaking when i enable both.
after a couple of hour kamailio stops and spams error messages.

Troubleshooting

kamcmd pkg.stats shows lots of real_used memory(only udp workers are leaking).

Reproduction

Enable both modules.
