Using earls with some hashtags that are getting more loads, I'm getting lots of EventEmitter exceptions like this one:

Looking around I found it's a common issue about how many emitter are available if I'm using streams with higher volume of tweets. This link contains some referral to it: https://github.com/request/request/issues/870

What version of node are you running?

[remagio]

node v0.10.29

Ok, that should be good. It's just a warning that more event listeners are being added. Nothing to be worried about. See https://stackoverflow.com/questions/9768444/possible-eventemitter-memory-leak-detected
