[alibaba/tengine]limit_conn_zone指令不起作用

为什么limit_conn_zone设置了不起作用？只能用limit_req_zone做限速吗？ PS：两个模块都已经安装，现在需求是不要限速，要做限并发，貌似Tengine做不了啊，确定配置没有问题，nginx一次通过，Tengine就是死活不行，是不是ngx_http_limit_conn_module模块给改了，急急急.......

ngx_http_limit_conn_module模块跟官方是一样的，没有改动，本地大文件测试了下是生效的。可以把配置和测试方法贴一下，看看中间是不是有什么问题。

Tengine之limit_conn_zone并发测试结果.docx

测试方法如下：
  1. Tengine：Tengine/2.2.2 (nginx/1.8.1)
  2. Nginx：nginx/1.7.4
  3. 测试工具：siege 4.0.4
    Tengine与Nginx进行相同配置如下：
    
#http段：
http {
……
limit_conn_zone $binary_remote_addr zone=ip_limit:15m;
……
}
server段：

server {

location / {
     limit_conn  ip_limit 10;
     limit_conn_status 500;
        root   /usr/local/webserver/nginx/html/web;
        index  index.php index.html index.htm;
    }

}

#### 测试Tengine：

siege -c 15 -r 1 www.zhang.com SIEGE 4.0.4 Preparing 15 concurrent users for battle. The server is now under siege...

测试结果: 15并发情况下全部通过，limit_conn ip_limit 10;没有起作用。


#### 测试Nginx：

测试结果： 15并发情况下，成功11个，拦截4个，并发数在往上加也是如此, limit_conn设置成功。
