server freeze during sending messages

[ghost]

I like your webscoket server its very helpful to me :] But i have a big problem sometimes when sending a message from the thread "a" the script freeze that happens after calling self.request.send(header + payload) Informations that can help: The server sends about 16packet/s for every client and there is on average 50 clients connected to the server on the same time, the script freeze once every 5minutes-2hours so i need to manualy restart the script everytime that happens and they need to reconnect. tested the script on both windows 10 and ubuntu 18,python 3.6 and python 3.7 and still the same problem.

a = threading.Thread(target=_script)
a.start()
server = WebsocketServer(13355,'0.0.0.0',dir)
server.set_fn_message_received(_read)
server.set_fn_client_left(_close)
server.run_forever()

also added ssl

def __init__(self, port, host, dir, loglevel=logging.WARNING):
        logger.setLevel(loglevel)
        TCPServer.__init__(self, (host, port), WebSocketHandler)
        self.port = self.socket.getsockname()[1]
        key_file = dir+'private.key'
        cert_file = dir+'certificate.crt'
        ca_file = dir+'ca_bundle.crt'
        self.socket = ssl.wrap_socket(self.socket, keyfile=key_file, certfile=cert_file, ca_certs=ca_file, cert_reqs=ssl.CERT_NONE)

Hey @ZeRo137 Does your traceback look like this? If so, I've got a similar issue.
