Under high throughput, lots of errors appear in the console like this: `MongoError: command find requires authentication` with error code `13`. I believe it is when a connection gets closed/times out and then reconnects we start seeing errors like this. It only ever happens under very high load with >200 requests/second executing ~4 queries per request.
MongoError: command find requires authentication File "/worker/node_modules/mongodb-core/lib/cursor.js", line 247, col 25, in queryCallback return callback(new MongoError(result.documents[0]), null); File "/worker/node_modules/mongodb-core/lib/connection/pool.js", line 531, col 18, in null.<anonymous> return cb(err, result); File "internal/process/next_tick.js", line 176, col 11, in process._tickCallback
MongoDB server is v4.0 (seen also on v3.6) running as a Docker container. The logs show no unauthorised errors related to these queries, only these unrelated ones:

Connection is initialised like this:
import mongoose from 'mongoose'; mongoose.Promise = global.Promise; const connectToMongoDB = () => { const opts = { keepAlive: true, keepAliveInitialDelay: 300000, socketTimeoutMS: 30000, poolSize: 50, reconnectTries: Number.MAX_VALUE, reconnectInterval: 500, autoReconnect: true, }; return mongoose.connect('mongodb://user:password@mongodb:27017/nanowire', opts); }; export default connectToMongoDB;
