AsyncTcpConnection总是掉线的问题？

问题描述

用TP6的框架和workerman异步从第三方网站获取链接，但是，在启动几分钟后就会自动停掉，也没有调用onClose方法。

程序代码

gateway_worker配置
 // BusinsessWorker配置
    'businessWorker'        => [
        'name'         => 'BusinessWorker',
        'count'        => 1,
        'eventHandler' => '\app\push\controller\Events',
    ],

class Events extends PushController
{
    public static function onWorkerStart($worker)
    {
     // 异步建立一个连接
            $con = new AsyncTcpConnection(sysconfig('api', 'test_api'));
            $con->transport = 'ssl';
            $con->onConnect = function ($con) {
                Log::error('onConnect');
                \app\push\controller\Test::onAsyncConnect($con);
            };
            $con->onMessage = function ($con, $message) use($worker) {
                Log::error('onMessage');
                \app\push\controller\Test::onAsyncMessage($con, $message, $worker);
            };
            $con->onClose = function ($con) {
                // 如果连接断开，则在1秒后重连
                Log::error('reConnect');

                Timer::add(5, array($con, 'connect'), null, false);

                $con->reConnect(1);
            };
            $con->onError = function ($con, $code, $msg) {
                //错误的通知处理
                Log::error('error:'.$msg);
            };
            // 执行异步连接
            $con->connect();
     }
}
