【问题描述】：

我在本地运行控制台时使用 Vagrant ssh 连接到远程 Grinder 代理：

vagrant ssh agent01 -c "./startAgent.sh" -- -R 6372:localhost:6372

控制台可以与代理对话，并启动代理的线程：

2015-07-24 10:12:54,391 INFO  agent: The Grinder 3.11
2015-07-24 10:12:54,507 INFO  agent: connected to console at /127.0.0.1:6372

2015-07-24 10:12:58,250 INFO  agent: worker agent01-9 started

不过，不久之后，特工们说：

2015-07-24 10:13:38,016 INFO  agent01-2: Report to console failed

...

永远不要向控制台提供数据。

这是什么原因造成的？我需要调整 ssh 配置吗？

标签： ssh vagrant ssh-tunnel grinder

【解决方案1】：

为了解决这个问题，我将这一行添加到磨床代理主机上的 /etc/ssh/sshd_config 中：

MaxStartups 1000

并将磨床代理属性更改为：

grinder.processes = 10
grinder.threads = 100

到

grinder.processes = 4
grinder.threads = 250
