一定时间后，节点应用无响应 [英] Node app unresponsive after certain amount of time
问题描述
我试图弄清楚为什么我的nodejs应用在11小时20分钟后变得无响应.不管我是在amazon-linux还是Red Hat上运行它，每次都会发生.
I'm trying to figure out why my nodejs app becomes unresponsive after 11h 20min. It happens every time, no matter if I run it on amazon-linux or Red Hat.
我的堆栈:
- nodejs(v.6.9.4)
- mongodb(3.2)
- pm2流程管理器
- AWS EC2实例T2介质
每次我运行该应用程序时，它都会响应并返回到浏览器，并变得无响应:
Every time I'm running the app it becomes unresponsive with an error returned to the browser:
net :: ERR_CONNECTION_RESET
net::ERR_CONNECTION_RESET
Pm2不会重新启动该应用程序，因此我怀疑它与nodejs无关，我也分析了该应用程序，并且它没有内存泄漏. db日志也看起来不错.
Pm2 doesn't restart the app, so I suspect it has nothing to do with nodejs, I also analysed the app and it doesn't have memory leaks. Db logs also look alright.
唯一不变的因素是该应用在运行11小时20分钟后崩溃.
我正在处理nodejs应用程序中的所有可能的错误，但是日志文件中没有错误发生，因此我怀疑这必须是其他原因.
I'm handling all possible errors from the nodejs app, but no errors in the log files occur so I suspect it has to be something else.
我还检查了var/log/messages和/home/centos/messages，但也与该应用程序的崩溃无关.
I also checked var/log/messages and /home/centos/messages but nothing related to the crash of the app there either.
/var/log/mongodb/mongo.log也不显示任何特定内容.
/var/log/mongodb/mongo.log doesn't show anything specific either.
解决问题的最佳方法是什么?
What would be the best way to approach the problem ?
任何提示我该如何调试它或是什么原因?
Any clues how can I debug it or what could be the reason ?
谢谢
推荐答案
从注释中复制，因为它显然导致了解决方案:
Copied from the comment since it apparently led to the solution:
我想，除了内存以外，您正在泄漏其他内容，也许是文件描述符.尝试使用netstat或lsof来查看打开的连接或文件是否比您预期的要多.
You're leaking something other than memory is my guess, maybe file descriptors. Try using netstat or lsof to see if there are a lot more open connections or files than you expect.
