我使用Vagrant ssh连接到远程Grinder代理，同时在本地运行控制台:
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 10:12:58,250 INFO agent: worker agent01-9 started
然而，不久之后，代理人说:
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。
是什么原因造成的?我需要调整ssh配置吗?
为了解决这个问题，我在grinder代理主机上的/etc/ssh/sshd_config中添加了这一行:
MaxStartups 1000
并将研磨剂属性更改为:
grinder.processes = 10
grinder.threads = 100
grinder.processes = 4
grinder.threads = 250
