Why does my query not working with more than 100 documents in collection?

db.collection('allowedmacs').find().toArray(function(err, docs) {
console.log(docs);
}

err says this:

name: 'MongoError',
message: 'connection destroyed, not possible to instantiate cursor'

If documents <100 all works fine.

You're probably doing something like this:

db.collection('allowedmacs').find().toArray(function(err, docs) {
  console.log(docs);
});
db.close();

So you're closing the database before the callback to toArray has been called (although it may work on some occassions).

Instead, try this:

db.collection('allowedmacs').find().toArray(function(err, docs) {
  console.log(docs);
  db.close();
});
