Hi, I would to know howto fix the warning: warning: possible EventEmitter memory leak detected. 51 open listeners added. Use emitter.setMaxListeners() to increase limit.

I seen that there are similar closed issues of it, but without real solutions.

if you see here (http://www.jongleberry.com/understanding-possible-eventemitter-leaks.html),
seems removeListeners is being missing
#117

Best Regards.

Running into this too, I am not sure, but I think it happens when there are too many queries executed, when mongoskin returned promise, but have not connected to database yet.

I usually do something like this:

var db = mongo.db(dbName, dbOptions);
db._emitter.setMaxListeners(0);

but have not connected to database yet

this is why,because if mongoskin has not connected to the database, it will register once('open') for the query to do queries when db connected
