为什么sockjs（在meteor中）一次又一次地提出同样的请求？,meteor,sockjs,Meteor,Sockjs,我的应用程序在生产过程中出现间歇性停机。在Amazon ALB（负载平衡器）和NGINX之后，我有3个应用程序实例。偶尔，我会看到一个应用程序服务器100%运行，并没有响应。最后，其他的盒子没有反应，并保持大约3个小时没有反应。重新启动应用程序正在运行的docker容器或重新启动EC2机器似乎没有帮助。这让我觉得在网络层面上发生了一些事情，影响了所有实例。在这一点上，我已经排除了大型数据集、长时间运行的操作、可怕的cron作业等，并且注意到了一系列我无法解释的/sockjs/请求 我确实看到的一

我的应用程序在生产过程中出现间歇性停机。在Amazon ALB（负载平衡器）和NGINX之后，我有3个应用程序实例。偶尔，我会看到一个应用程序服务器100%运行，并没有响应。最后，其他的盒子没有反应，并保持大约3个小时没有反应。重新启动应用程序正在运行的docker容器或重新启动EC2机器似乎没有帮助。这让我觉得在网络层面上发生了一些事情，影响了所有实例。在这一点上，我已经排除了大型数据集、长时间运行的操作、可怕的cron作业等，并且注意到了一系列我无法解释的/sockjs/请求

我确实看到的一件事是，在我的nginx日志中，有很多请求指向/sockjs/。通常，每次创建新的浏览器/客户端会话时，我只会看到一个这样的请求。下面是我们在过去5个小时连续收到的sockjs请求的一个示例。我截短了它，但模式重复。我还查看了这个用户会话（我们使用FullStory），并验证了用户在这段时间内并没有什么进展

有谁知道： -当我一遍又一遍地看到这些日志时，这意味着什么？ -是什么导致他们在一分钟内重复这么多次？ -我如何重现这种情况？（这似乎不是用户的恶意尝试） -这正常吗

为简洁起见，这里重复的部分是：
/sockjs/372/_7p3spix/xhr_send HTTP/1.1“204 0

下面是一个简要说明，说明它发生的频率
