У меня следующая конфигурация WebSocket: 

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig implements WebSocketMessageBrokerConfigurer {
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/game");
        registry.addEndpoint("/game").withSockJS();
    }

    @Override
    public void configureClientInboundChannel(ChannelRegistration registration) {
        registration.interceptors(subscriptionInterceptor());
    }

    @Override
    public void configureClientOutboundChannel(ChannelRegistration registration) {
    }

    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/all","/user", "/table");
        config.setApplicationDestinationPrefixes("/app");
        config.setPreservePublishOrder(true);
    }

    @Override
    public void configureWebSocketTransport(WebSocketTransportRegistration registry) {
        registry.setMessageSizeLimit(5 * 1024 * 1024);
        registry.setSendBufferSizeLimit(5 * 1024 * 1024);
        registry.setSendTimeLimit(60 * 1000);
    }

    @Bean
    public SubscriptionInterceptor subscriptionInterceptor() {
        return new SubscriptionInterceptor();
    }
}

У меня около 30 JS клиентов, подключенных к моему серверу с помощью Sock JS для отправки сообщений. Время от времени я получаю следующую ошибку:

Я понятия не имею, почему я получаю такую ​​ошибку. Я искал все в inte rnet, но я не нашел решения этой проблемы, или, по крайней мере, кто-то, кто может объяснить, что происходит.

Благодарен, если опытный программист с Spring и Websocket может помочь.
