Trouble getting a response from cursor.toArray() in Mongo/Node

Question

node 0.10.24 + mongo node driver 1.3.23 on 32 bit linux

My callback here is never getting executed.

  console.log(record_collection);
  record_collection.find({}, function (error, cursor) {

    console.log("record_collection.find() returned");

    if (error) {
      console.log(error);
      callback(error);
    }
    else {

      console.log("calling toArray with cursor");

      cursor.toArray(function(error, docs){

        console.log("cursor.toArray() returned");

        if (error) {
          console.log(error);
          callback(error);
        }
        else {
          callback(null, docs);
        }

      });
    }
  });

The output from this section goes like this:

record_collection.find() returned
calling toArray with cursor

It looks like the first console.log() of the collection doesn't finish. But the other traces appear. Why isn't the callback being executed? Why don't I see "cursor.toArray() returned"?

This stopped working when I moved to a new server. The old server was running node 0.10.13 and mongodb 1.2.13.

Answer 1

From the record_collection trace:

db.serverConfig.connected = false;

The database was not connected.
