Radius TCP/TLS client connection timed out

Logged when an established RADIUS stream connection carried no traffic for its configured idle timeout and is closed. The timeout_ms and reply_frames fields describe the connection state. Closing unused connections is routine; the client opens a new connection when it next has traffic.

No action. If clients keep many connections open with little traffic and you want them to stay open longer, increase the listener timeout or the overriding client timeout.
