### Description On server used WebRTC clients. Some time Kamailio start flooding messages like this ``` INFO: websocket [ws_frame.c:814]: ws_keepalive(): tcp connection has been lost ``` I have enabled debug logs and can see more detailed output. ``` INFO: websocket [ws_frame.c:814]: ws_keepalive(): tcp connection has been lost DEBUG: websocket [ws_conn.c:485]: wsconn_put_id(): wsconn put id [49] DEBUG: websocket [ws_conn.c:490]: wsconn_put_id(): wsc [0xffff7b4af448] refcnt [2] DEBUG: websocket [ws_conn.c:425]: wsconn_put_mode(): wsconn_put start for [0xffff7b4af448] refcnt [2] DEBUG: websocket [ws_conn.c:439]: wsconn_put_mode(): wsconn_put end for [0xffff7b4af448] refcnt [1] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [52] DEBUG: websocket [ws_conn.c:467]: wsconn_get(): wsconn_get returns wsc [0xffff7b4df8f8] refcnt [2] INFO: websocket [ws_frame.c:814]: ws_keepalive(): tcp connection has been lost DEBUG: websocket [ws_conn.c:485]: wsconn_put_id(): wsconn put id [52] DEBUG: websocket [ws_conn.c:490]: wsconn_put_id(): wsc [0xffff7b4df8f8] refcnt [2] DEBUG: websocket [ws_conn.c:425]: wsconn_put_mode(): wsconn_put start for [0xffff7b4df8f8] refcnt [2] DEBUG: websocket [ws_conn.c:439]: wsconn_put_mode(): wsconn_put end for [0xffff7b4df8f8] refcnt [1] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [61] DEBUG: websocket [ws_conn.c:467]: wsconn_get(): wsconn_get returns wsc [0xffff7b57bfa0] refcnt [2] INFO: websocket [ws_frame.c:814]: ws_keepalive(): tcp connection has been lost DEBUG: websocket [ws_conn.c:485]: wsconn_put_id(): wsconn put id [61] DEBUG: websocket [ws_conn.c:490]: wsconn_put_id(): wsc [0xffff7b57bfa0] refcnt [2] DEBUG: websocket [ws_conn.c:425]: wsconn_put_mode(): wsconn_put start for [0xffff7b57bfa0] refcnt [2] DEBUG: websocket [ws_conn.c:439]: wsconn_put_mode(): wsconn_put end for [0xffff7b57bfa0] refcnt [1] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [70] DEBUG: websocket [ws_conn.c:467]: wsconn_get(): wsconn_get returns wsc [0xffff7b5cc770] refcnt [2] INFO: websocket [ws_frame.c:814]: ws_keepalive(): tcp connection has been lost DEBUG: websocket [ws_conn.c:485]: wsconn_put_id(): wsconn put id [70] DEBUG: websocket [ws_conn.c:490]: wsconn_put_id(): wsc [0xffff7b5cc770] refcnt [2] DEBUG: websocket [ws_conn.c:425]: wsconn_put_mode(): wsconn_put start for [0xffff7b5cc770] refcnt [2] DEBUG: websocket [ws_conn.c:439]: wsconn_put_mode(): wsconn_put end for [0xffff7b5cc770] refcnt [1] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [0] DEBUG: websocket [ws_conn.c:461]: wsconn_get(): wsconn_get for id [76] DEBUG: websocket [ws_conn.c:467]: wsconn_get(): wsconn_get returns wsc [0xffff7b62d0d0] refcnt [2] INFO: websocket [ws_frame.c:814]: ws_keepalive(): tcp connection has been lost ``` On the server installed commit 1d03d9e8312e6e9b494f6d243fe9b2b4ea890eaf ### Troubleshooting I do not know.
