Thanks, Daniel @miconda The real issue is that Kamailio stopped processing WebRTC clients/connections and I need to restart Kamailio daemon.
Rate of this info message to high and we do not have such an amount of WebRTC clients. For me, it looks like some loop in the connection handling.
I will try to collect additional info when the issue is reproduced. I want test: 1. TCP SIP clients message processing; 2. UDP client processing; 3. basic HTTP request handling.
