Openshift,503服务不可用.没有服务器可用于处理此请求

Question

我在Openshift上有一个可扩展的PHP 5.4盒式磁带,带有一个青铜帐户.这是一个wordpress博客,我已经使用它直到2周前.

今天,我回来参观了它,它说:

503服务不可用.没有服务器可用于处理此请求.

为了检查代理状态,我访问了这个链接http://myapp-mydomain.rhcloud.com/haproxy-status,我看到了这个:

好像DOWN.

使用rhc tail检查日志我看到这一行:

    ==> app-root/logs/haproxy.log <==
[ALERT] 077/194638 (138628) : proxy 'express' has no server available!

[ALERT] 086/161325 (33522) : proxy 'express' has no server available!

我也尝试使用openshift"重启"按钮重启应用程序,但它没有用.

不知道该怎么解决.任何的想法？

提前致谢

您的免费 OpenShift 齿轮由未使用的处理/带宽功率来处理。如果目前没有服务器可用于运行您的应用程序的 gears，则发出的请求将被拒绝，并显示“503 服务不可用：没有服务器可用于处理此请求”。

如果您想确保应用程序的正常运行时间，请使用付费装备。
