GatewayWorker 压测并发卡在3000

问题描述

GatewayWorker 压测在3000多的时候就上不去了,报 worker[none:3956] exit with status 9
服务器：2核4G ; centos

这里写问题具体描述
内核已经按照文档优化：



按照https://www.workerman.net/doc/workerman/debug/busy-process.html 追踪：

也并没有什么可疑点
以下是压测代码

<?php
require_once __DIR__ . '/../../vendor/autoload.php';
use Workerman\Worker;
use Workerman\Lib\Timer;
use Workerman\Connection\AsyncTcpConnection;

/**
 * 连接数压力测试demo
 */
$worker = new Worker();
$worker->onWorkerStart = 'connect';
function connect(){
    static $count = 0;
    // 5000个链接
    if ($count++ >= 5000) return;
    // 建立异步链接
    //
    $con = new AsyncTcpConnection('ws://danmu.demo.live');
    $con->transport = 'ssl';
    $con->onConnect = function($con) {
        // 递归调用connect
        connect();
    };
    $con->onMessage = function($con, $msg) {
        echo "recv $msg\n";
    };
    $con->onClose = function($con) {
        echo "con close\n";
    };
    // 当前链接每30秒发个心跳包
    Timer::add(30, function()use($con){
        $con->send('ping');
    });
    $con->connect();
    echo $count, " connections complete\n";
}
Worker::runAll();

以下是Events.php中connect的代码：

  // 定时关闭未认证的连接
    public static function onConnect($client_id)
    {
        // 连接到来后，定时30秒关闭这个链接，需要40秒内发认证并删除定时器阻止关闭连接的执行
        $_SESSION['auth_timer_id'] = Timer::add(40, function($client_id){
            Gateway::closeClient($client_id);
        }, array($client_id), false);
    }

谢谢！
