为什么Azure的给我一个间歇性错误503服务不可用？ [英] Why does Azure give me an intermittent Error 503. The service is unavailable?

问题描述

我有一个已经运行的很长一段时间的Azure的服务。它建立基于在请求参数的字或PowerPoint文档，并返回的URI到构建文档。这是通过一个Visualforce则页面访问，当你点击一个按钮，它会调用服务并显示一个链接到刚刚建成的文档。简单的。

I have an Azure service that has been running for a long period of time. It builds a word or powerpoint document based on arguments in the request and returns a uri to the build document. This is access via a visualforce page, when you click a button, it calls the service and displays a link to the document that has just been built. Simple.

突然，我得到一个明显的随机503服务不可用错误。有时候，我按一下按钮，没有问题。其他时候，一个503错误。每次按钮会触发完全相同的请求。没有人知道为什么这可能发生？

All of a sudden, I get an apparently random 503 Service Unavailable error. Sometimes I click the button, no problem. Other times a 503 error. Each time the button triggers exactly the same request. Does anyone know why this might be happening?

显然做同样的事情一遍又一遍，并期待不同的结果，是不是精神错乱！

Apparently doing the same thing over and over again and expecting a different result, is not insanity!

推荐答案

看着我的服务监控告诉我，该处理器从来没有超过使用量的6％，所以它不可能是导致这些间歇性的503缺乏资源错误。这是奇怪的，我怕我没有解释它，而只是重新部署云服务天青似乎做的伎俩。现在它完美地工作。该解决方案还没有改变，所以我只能想象，无论'重启'是必要的部署后，已纠正无论问题是。所有我可以建议是，你做同样的事情，如果你得到间歇性错误503

Looking at the monitoring on my service told me the processor was never exceeding 6% of usage, so it couldn't be a lack of resource causing these intermittent 503 errors. It's bizarre and I'm afraid I have no explanation for it, but simply redeploying the cloud service to Azure appears to have done the trick. It now works perfectly. The solution has not changed, so I can only imagine that whatever 'reboot' is necessary after deployment, has rectified whatever the problem was. All I can suggest is that you try the same thing if you are getting intermittent 503 errors.
