it happen in swoft framework, when use RPC services are integrated in Http Server startup

    'httpServer' => [
        'class' => HttpServer::class,
        'port' => env('HTTP_PORT', 18306),
        'listener' => [
            'rpc' => bean('rpcServer'),
            // 'tcp' => bean('tcpServer'),
        ],

    /**
     * Add listener serve to the main server
     *
     * @throws ServerException
     */
    protected function addListener(): void
    {
        foreach ($this->listener as $listener) {
            if (!$listener instanceof ServerInterface) {
                continue;
            }

            $host = $listener->getHost();
            $port = $listener->getPort();
            $type = $listener->getType();

            if (!$events = $listener->getOn()) {
                throw new ServerException(
                    'Not add any event handler for the listener server: ' . get_class($listener)
                );
            }

            /* @var CoServer\Port $server */
            $server = $this->swooleServer->listen($host, $port, $type);
            $server->set($listener->getSetting());

            // Bind events to the sub-server
            $this->addEvent($server, $events);

            // Trigger event
            Swoft::trigger(ServerEvent::AFTER_ADDED_LISTENER, $server, $this);
        }
    }

it happen maybe about 2 times one day error logs
