Hello, It seems we have the same problem, it doesn't happen often, but the Register part of internal profile does crash. I observe that the number of connections established on the WSS port (7443) sometimes exceeds the number of active registrations. (netstat -tpa).. It could be really important (2 or 3 times the number of Registrations), it could of course be a software problem on the WebRTC (Front) client side. Is there a way on the Freeswitch side in the configuration to disconnect TLS connections that are no longer registered? On timeout for example. Best regards.

I am in production with 1.10.5 version and since a week, I have the same issue. The internal profile is out of service and registration is impossible. and we don't have any answer to "sofia status profile internal" , the prompt in fs_cli keeps waiting. the only way to solve is to restart freeswitch thanks regards
