MongoError: Topology was destroyed
I have a REST service built in node.js with Restify and Mongoose and a mongoDB with a collection with about 30.000 regular sized documents. I have my node service running through pmx and pm2.
Yesterday, suddenly, node started crapping out errors with the message "MongoError: Topology was destroyed", nothing more. I have no idea what is meant by this and what could have possibly triggered this. there is also not much to be found when google-searching this. So I thought I'd ask here.
After restarting the node service today, the errors stopped coming in. I also have one of these runnings in production and it scares me that this could happen at any given time to a pretty crucial part of the setup running there...
I'm using the following versions of the mentioned packages:
mongoose: 4.0.3
rectify: 3.0.3
node: 0.10.25
To solve mongoerror: topology was destroyed for better production you can use the following way:
var options = {
server: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } },
replset: { socketOptions: { keepAlive: 1, connectTimeoutMS: 30000 } }
};
mongoose.connect(secrets.db, options);
