请教大神，ngrinder相关ERROR Read timed out的错误，超时时间可以在哪边设置呢？

增大并发后，报了如下错误：

请问Read timed out的超时时间可以在哪边进行设置呢？ 求大神指点哈~ 谢谢

[soul]

继续追加一个问题哈~~  请问在脚本中，可以通过什么方法，加载到测试配置里的“测试次数”呢？试了用System.getProperty("grinder.duration")返回为null

[WaitUntil]

HTTPPluginControl.getConnectionDefaults().timeout = 8000

脚本里修改，8秒超时

[soul]

Hi~WaitUntil：
感谢回答，以上报错内容，是在脚本已经修改为120秒的背景下依旧报错：
HTTPPluginControl.getConnectionDefaults().timeout = 120000
请问有其他方法可以进行Read time的相关设置吗？
