### 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.

If only the info message is a concern, then the `debug` parameter can be set to 1. The
info logs are sort of special 'debug' messages that can occur many times and the
solution is to lower `debug` threshold. It is not unusual that connections are lost
because of client side or intermediary nodes like nat or ip routers, firewalls, ...
If you want to suggest turning info to debug message in this case, then over the time we
can end up only with two log levels **debug** and **print-always** (or **error**), while
the current design with many more log levels expect that **info** level can still be
pretty verbose, but not as **debug**.
Besides info messages, I don't see errors, so I am not sure what you mean with the
remark in the title that **cannot be terminated**. It may take time to be removed from the
internal list, clean up being done on timer. Or maybe you can elaborate more what is the
exact problem: the info logs or something else behind that.

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.

Issue reproduced and kamcmd I can see
```
kamcmd> ws.dump

}
info: {
wscounter: 4
truncated: no
}
}
```
I closed all connections using `ws.close` and a new connection was created again from the
client.
The same error message was generated for the new WebSocket connection.

For me, it looks like for some reason connection cannot be removed.
Also according to GDB `*wsc` connection from port 52472 but not such connection in kamcmd
output
```
kamcmd> [root@ippbx-0b tmp]# kamcmd ws.dump

I have cherry-picked commit e7bd1570e3788e9d04047b4d1d00cb8bd8b172d3 into 5.6 branch and
installed it on the server.
Now I can see WebSocket ID in Kamailio logs but cannot find it in the log the WebSocket
connection is created.
Now I can ln the Kamailio log.
```
INFO: WebSocket [ws_frame.c:814]: ws_keepalive(): tcp connection has been lost (id: 34
wsc: 0xffff7e390d90)
```
In the log, I found when the connection created
```
INFO: <script>: websocket|log|opened websocket 34 from 2605:84c0:90:11::101:60157
```
PCAP for TCP connection via port 60157 is attached.
[tcp_60157.pcap.gz](https://github.com/kamailio/kamailio/files/10417302/tcp_…
For me looks like the WebSocket TCP connection closed properly.
But Komilio is cleaning not all memory structures related to this connection.

9:55 a.m.
I created this GDB script
```
define check_wsc
while(wsc->state == WS_S_REMOVING)
p wsc->id
p wsc->rmticks
cont
end
end
at 183996
b ws_conn.c:694
condition 1 wsc->state == WS_S_REMOVING
set pagination off
c
check_wsc
```
Where I watch the process with 183996 is `WEBSOCKET TIMER`.
```
[root@ippbx-0a ~]# kamcmd ps | grep WEBSOCKET
183989 WEBSOCKET KEEPALIVE
183992 WEBSOCKET KEEPALIVE
183994 WEBSOCKET KEEPALIVE
183996 WEBSOCKET TIMER
```
Script output shows the webssocket `rmticks` always increased and timeout for
`rm_delay_interval` never fired.
For me that is a reason why websocket connection cannot be closed.
```
(gdb) c
Continuing.

This happens because of race conditions with websocket state.
[ws_frame.c:816](https://github.com/kamailio/kamailio/blob/ac4c2d4579f121395…
- setting socked state `WS_S_CLOSING`
[ws_conn.c:703](https://github.com/kamailio/kamailio/blob/master/src/modules…
- setting socket state `WS_S_REMOVING` and updates `rmticks` value.
I will create a pull request to break race conditions.
