<h3>Description</h3>
<p>I used a MCU with kamailio proxy which enabled the websocket module,<br>
and made 13 WebRTC clients (same domain as the MCU) was connected to the MCU orderly,<br>
then let MCU disconnected them all orderly and quickly.<br>
After that, WSS port can't be accessd anymore - but it not always happens!</p>
<p>However , whether it's blocked or not,<br>
It can be found that the receiving queue of kamailio had value left and this shouldn't happen:</p>
<blockquote>
<p>Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name<br>
tcp 0 0 10.100.92.222:10443 0.0.0.0:* LISTEN 6851/kamailio<br>
tcp 1 0 10.100.92.222:10443 10.100.92.35:50283 CLOSE_WAIT 6812/kamailio<br>
tcp 1359 0 10.100.92.222:10443 10.100.92.35:50249 CLOSE_WAIT 6817/kamailio</p>
</blockquote>
<p>Btw, I tried to find the cause by myself ever with lots of log added,<br>
it seems that the process stuck in the function tls_read() in tcp_read.c,<br>
(so the following TCP/TLS packets can be handled)<br>
following is my tracing procedure , perhaps this can help you to clarify the issue. :)</p>
<p>tcp_read.c:<br>
---> tcp_read_req()</p>
<pre><code> if (likely(req->error==TCP_REQ_OK)){
#ifdef READ_WS
if (unlikely(con->type == PROTO_WS || con->type == PROTO_WSS))
bytes=tcp_read_ws(con, read_flags);
else
#endif
bytes=tcp_read_headers(con, read_flags);
</code></pre>
<p>--->tcp_read_ws()</p>
<pre><code>#ifdef USE_TLS
if (unlikely(c->type == PROTO_WSS))
bytes = tls_read(c, read_flags); //<--- stuck here!!
