其实就是端口不够用了，需要按照要求继续配置即可

1.我们在短时间内跑大量的请求时将端口占满了，导致如上报错。

解决办法（在jmeter所在服务器操作）：

1.cmd中输入regedit命令打开注册表；

2.在 HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters右键Parameters；

3.添加一个新的DWORD，名字为MaxUserPort；

4.然后双击MaxUserPort，输入数值数据为65534，基数选择十进制；

5.完成以上操作，务必重启机器，问题解决。

解决后的测试结果就不再报错：
