我正在运行使用Phusion Passenger部署的Meteor应用程序，并且最近注意到该应用程序间歇性地死亡并且重新启动时出现问题。它大多数时间都有效，而且我还没有更新它一个月或更长时间。我认为我的设置必须基本正确，否则根本无法正常工作。
这似乎与分块有关，遗憾的是我不知道那是什么或如何调试它。
我试过sudo service nginx restart，但问题又重演了。
对于乘客日志级别3，我看到了这个错误：
phusion passenger Disconnecting client with error: error parsing app response chunked encoding: unexpected end-of-stream
以下是/var/log/nginx/error.log的示例输出，其乘客日志级别设置为7：

我的设置：
乘客5.1.12 / nginx
Server是运行Ubuntu 16.04的Digital Ocean Droplet
使用Meteor 1.6.0.1构建的应用程序
https://www.phusionpassenger.com/library/walkthroughs/deploy/meteor/
我在这台服务器上运行3个应用程序，所有应用程序都使用相同版本的Meteor构建，并在Passenger下运行，没有其他明显问题。
是否有人知道可能导致此问题的原因以及如何解决此问题？
