“服务器x超时”在MongoDB聚合期间 [英] "Server x timed out" during MongoDB aggregation
问题描述
error：{[MongoError：server< x> timed out]
name：'MongoError'，
message：'server< x>超时'$ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $ $它在2米左右时间超时）。有没有人有其他调试提示？ 2分钟的事情给我的印象是，我只需要在某处设置一些超时，但我无法弄清楚在哪里或者我只是陷入了一个红色的鲱鱼陷阱。
关于系统配置：此聚合脚本是在基于alpine的docker（v1.9.1）容器中运行的node.js（v5.9.1）应用程序。它使用 mongodb 节点驱动程序（v2.1.19）。运行mongod（v3.2.6）
解决方案我的单个mongodb服务器（尽管这也在一个单独的环境中使用replSet）日志时间聚合也遇到同样的问题。我想我有解决方案。
我发现选项 socketTimeoutMS 是负责的。
检查您的mongo_client.js默认值 socketTimeoutMS 值。对我来说，它是 2分钟。 Mongodb模块版本2.1.18。
所以只需将这个选项添加到你的url中：
code> mongodb：// localhost：27017 / test？maxPoolSize = 2& socketTimeoutMS = 60000
它会将 timeout 设置为10分钟。这对我来说是个伎俩。
I have a script that periodically runs aggregation on a mongodb collection. As the dataset has grown, the amount of time it takes to aggregate has also grown. My aggregation script has recently stopped working consistently, and the error logs show:
error: { [MongoError: server <x> timed out]
name: 'MongoError',
message: 'server <x> timed out' }
I've tried debugging this, and the only pattern I can find is that this timeout seems to only occur when the aggregation takes longer than 2 minutes (it times out right around 2m). Does anyone have additional debugging tips for this? The 2-minute thing is giving me the impression that I just need to configure some timeout somewhere but I can't figure out where or if i'm just falling into a red-herring trap.
About the system configuration: This aggregation script is a node.js (v5.9.1) application running in an alpine-based docker (v1.9.1) container. It uses the mongodb node driver (v2.1.19). Single mongodb server (though this is also happening in a separate environment with a replSet) running mongod (v3.2.6)
I got the same problem for logs time aggregation. I think I have the solution for you.
I found that the option socketTimeoutMS is responsible for that.
Check your mongo_client.js default socketTimeoutMS value. For me it was 2min. Mongodb module version 2.1.18.
So just add this option into your url :
mongodb://localhost:27017/test?maxPoolSize=2&socketTimeoutMS=60000
It will set timeout to 10 mins. That does the trick for me.
