hello！
swoole-1.8.4
swoole_websocket_server连续接受小于8字节数据包后中断接受客户端消息包，客户端可以收到server的消息，swoole_websocket_server回调中断。

这个是配置问题么？

<?php

$ws = new swoole_websocket_server("101.200.214.88", 9502);

$ws->on('open', function ($ws, $request) {
    var_dump($request);

});

$ws->on('message', function ($ws, $frame) {

    echo "receive";
    var_dump($fd,$from_id,$data);

});


$ws->start();

?>

client.php

<?php
include_once '../init.php';
include_once 'WebSocketClient.php';

$client = new WebSocketClient("101.200.214.88", 9502);
$data = $client->connect();
for($i=0;$i<1000;$i++){
    $client->send("aaaaa".$i);
}

sleep(1);

测试运行结果如下:

把client.php中的send改为:

只有数据包小于8字节才会出现这个情况。 不需要太多次，连续两次就会断掉

是客户端断掉连接还是服务器断掉连接？
客户端连续向服务器发送8字节的内容吗？
服务器端有什么错误日志？

是客户端断掉连接还是服务器断掉连接？
socket链接没有断。是message回调函数不能再接收到客户端的消息。生产环境中，客户端能接收到server断推送的消息，server的回调函数不能再接收到客户端发送的消息。

客户端连续向服务器发送8字节的内容吗？
连续发送小于8字节。大于8字节不会出现这个情况。

服务器端有什么错误日志？
服务器没有任何报错。只有当客户端大循环的时候才会出现下边错误。
