Program consumes all the RAM on both server and client

Question

I have a separate file that only takes the camera and puts it on the screen and nothing happens, but when I add the part of sending it through the socket to the server, it begins to consume RAM until it reaches 100% (I have a PC with 32G RAM, so low capacity is not a problem).

SERVER

hostname = socket.gethostname()
ip = socket.gethostbyname(hostname)

HOST = "x"   
PORT = 9090

server = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server.bind((HOST, PORT))

server.listen()

clients_list = []


def broadcast_all(package):
    pass

def handle(client):
    while True:
        try:
            
            package = client.recv(1024)
            broadcast_all(package)
      
        except:
         
            index = clients_list.index(client)
            clients_list.remove(client)
            client.close()
            break

def receive():
    
    while True:
        client, address = server.accept()    

        print(f"Conectado desde {str(address)}")
        clients_list.append(client)

     
        handle_thread = threading.Thread(target=handle, args=(client))
        handle_thread.start()

print("Server Run")
receive()

CLIENT

HOST = 'X'  
PORT = 9090  

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect((HOST, PORT))


def visualizar():
    global cap
    if cap is not None:
        ret, frame = cap.read()

        if ret == True:
            frame = imutils.resize(frame, width=640)
            frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)

            im = Image.fromarray(frame)
            img = ImageTk.PhotoImage(image=im)

            label_video.configure(image=img)
            label_video.image = img

            sock.send(pickle.dumps(im))
            label_video.after(100,visualizar)
        

        else:
            label_video.image = ''
            cap.release()


def iniciar():
    global cap
    cap = cv2.VideoCapture(0, cv2.CAP_DSHOW)
    t1 = threading.Thread(target=visualizar)
    t1.start()
    


def terminar():
    global cap
    cap.release()

Is there any way that I don't consume all the RAM?
