No idea what this means. After 50 reloads this will appear in console log.

#6247 maybe same error?

[AysadKozanoglu]

to fix it:

require('events').EventEmitter.defaultMaxListeners = Infinity;  

[FredLackeyOfficial]

@AysadKozanoglu : Could you be more specific? I'm seeing this on a new machine / new install while running npm install on a project.

[MaestroJurko]

I am also seeing this error with 6.6 version of node when doing npm install.

[evolross]

I see this on my Galaxy logs. Using Meteor 1.5.1.

[scottstensland]

seeing this on METEOR@1.7.0.5
Does anyone have any suggestions ?

I had this error once. I solved it by placing the code in a separate Fiber like so:

// running job in a Fiber, if running without there will be a memory leak error
// (possible EventEmitter memory leak detected. 11 listeners added)
Fiber(function () {
    // code that causes the error
}).run();

I can't recall how I came up with the solution, but it worked for me.
