ECONNREFUSED on runtime

Working with Data Drivers
,

Hi all,

I am running a web app which daily is receiving lots of data and hence manipulating them and storing them into the database. The web app has an open connection for storing the data and the data is received by scrapers multiple times a day.

Mongodb throws the following error unexpectedly at times where I don’t even have a clue what’s causing it and where:

MongoServerSelectionError: connect ECONNREFUSED 127.0.0.1:27017
  at Timeout._onTimeout (/var/www/website.com/node_modules/mongodb/lib/core/sdam/topology.js:439:30)
  at listOnTimeout (internal/timers.js:555:17)
  at processTimers (internal/timers.js:498:7) {
reason: TopologyDescription {
  type: 'Single',
  setName: null,
  maxSetVersion: null,
  maxElectionId: null,
  servers: Map(1) { 'localhost:27017' => [ServerDescription] },
  stale: false,
  compatible: true,
  compatibilityError: null,
  logicalSessionTimeoutMinutes: null,
  heartbeatFrequencyMS: 10000,
  localThresholdMS: 15,
  commonWireVersion: 9
}}

This makes me having to stare at the website 24/7 because I simply don’t know when this error will happen and why. After spending hours researching, all the answers are about starting mongodb the right way, but my problem is not this. The problem is that mongodb starts when I restart my server, but during the runtime, mongodb will be completely disconnected.

What can I do in this case? Sadly, I am not a mongodb guru…

means that you application is trying to connect to a local instance of MongoDB that is currently down.

A server like MongoDB will terminate for 2 reasons:

  1. You terminate it yourself
  2. It crashes

In both cases the logs are needed for further investigation.

Hi Steve,

Thank you for your answer. I was wondering where I could find the logs to investigate this problem?

The location is specified in your configuration file.

If not specified, you will find the defaults at

Hi Steve,

I finally managed to get the logs from the mongodb (the file was 24G) and got the error:
