我已将Openshift升级为青铜计划，但我的申请经常停止，我不知道它是否空转或是错误。 这是我的尾部命令（rhc tail -a chat）的结果：

我不知道这是一个错误还是只是应用程序闲置。 抱歉我的英文不好，谢谢你
答案 0 :(得分：0)
在OpenShift v2上的缩放应用程序中，只要没有后端服务器通过运行状况检查，您就可以从haproxy获得503。所以当你看到这样的消息时：
[WARNING] 072/081559 (19871) : Server express/local-gear is DOWN, reason: Layer7 timeout, check duration: 10001ms. 0 active and 0 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
[ALERT] 072/081559 (19871) : proxy 'express' has no server available!
这意味着您的后端服务器全部失败，并且其中的原因是超时。您的健康检查URL必须在10秒内响应才能被视为健康。我不知道你的nodejs应用程序有什么问题，但空转肯定不是问题。
