EventEmitter memory leak detected.

[ultimatelocal]

Good day,

I'm getting this warning message whenever I'm starting my ember server and I don't know what causes ember-cli-meta-tags to ask for more listeners but for now, I'm using this quick fix process.setMaxListeners(21) on my ember-cli-build.js.

The warning goes away when I have process.setMaxListeners(21). Is this the right approach?

https://github.com/ember-cli/ember-cli/pull/5987 is also suggesting to increase process.setMaxListeners.

(node) warning: possible EventEmitter memory leak detected. 11 exit listeners added. Use emitter.setMaxListeners() to increase limit.
