unable to connect to tcp://0.0.0.0:2346(Address already in use)

http_server_test.php 代码

use Workerman\Worker;
require_once __DIR__ . '/Autoloader.php';

// Worker::$daemonize = true;
// 创建一个Worker监听2345端口，使用http协议通讯
$http_worker2 = new Worker("http://0.0.0.0:2346");

$http_worker2->name='25k_step2222';

$http_worker2->user='root';

$http_worker2->count = 3;

$http_worker2->onMessage = function($connection, $data)
{
    // 向浏览器发送hello world
    $connection->send('hello world from worker2');
};

// 启动4个进程对外提供服务
$http_worker1 = new Worker("http://0.0.0.0:2345");
$http_worker1->count = 5;
$http_worker1->name='25k_step1';
$http_worker1->user='www-data';
// 接收到浏览器发送的数据时回复hello world给浏览器
$http_worker1->onMessage = function($connection, $data)
{
    // 向浏览器发送hello world
    $connection->send('hello world from worker 1');
};

// 运行worker
Worker::runAll();

非deamon模式，PHP 7.0.18-0ubuntu0.16.04.1 (cli) ( NTS )
以下为自己打印的日志

initd只走一次，不管new了多少个woker
timer_init pcntl_signal,— 为进程: 1646安装一个sigalrm信号
pcntl_signal(SIGALRM 完毕
我启动 Workerman start 用 DEBUG 模式
先获取下进程pid1634
我启动时没有用了-d模式启动，那这句话会输出
没有设置demoniz,直接返回2-1
workername: 25k_step2222 changelength: 12
socketname: http://0.0.0.0:2346 changemaxlength: 19
当前用户id: 0 当前进程执行用户 {"name":"root","passwd":"x","uid":0,"gid":0,"gecos":"root","dir":"\/root","shell":"\/bin\/bash"}人为设置的当前进程用户: root
没有reuseport,调用listen 在initWorkers
listen begin================================================listen begin
transport: tcp scheme: http address : //0.0.0.0:2346
当前scheme http不在{"tcp":"tcp","udp":"udp","unix":"unix","ssl":"tcp"}那默认transport全都是:tcp
this的protocal设置为 ：\Protocols\Http
\Protocols\Http这个类不存在，我需要再设置一下
this的protocal设置又被设置为 ：\Workerman\Protocols\Http
所以到现在我的local_socket为: tcp://0.0.0.0:2346

已经看了手册 ：http://doc3.workerman.net/faq/workerman-start-fai
如果执行了reload 或者restart 也不行，删除pid文件也不行，killallphp 也不行 kill pid内的进程已经无效，关掉当前会话窗口也不行。。求教。。出现这个原因是啥？生产环境也有类似的问题。

最后解决办法是用top，发现一个php占用内存达到70%以上，kill 掉之后，一切正常。
