Appium 1.6.0-beta3 memory leak

Issues/Bugs
1

On my build server, at random times my tests are failing and i am getting an error:

(node:5558) Warning: Possible EventEmitter memory leak detected. 11 timeout listeners added. Use emitter.setMaxListeners() to increase limit

Firstly is anyone else getting this problem?

I think it is causing a red herring in some of my logs as i have also seen this:

15:34:17 Failure in before hook:Hooks.setup()
15:34:17 Message: org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
15:34:17 Build info: version: ‘2.53.1’, revision: ‘a36b8b1cd5757287168e54b817830adce9b0158d’, time: ‘2016-06-30 19:26:09’

A normal system out i put in code happens 20 minutes before, so it looks like the whole project is hanging for some reason, possibly from a memory leak?

Yes I got the same error while I was running iOS test using XCode 8 and Appium 1.6.0 beta.
