Odd error in command box

I have a command script that runs that opens several webpages and programs automatically. It's worked great for years but lately it stops and throws an error message saying:

(node:9804) MaxListenersExceededWarning: Possible EventEmitter memory leak detected. 11 appInitialized listeners added. Use emitter.setMaxListeners() to increase limit

Does anyone know what this means or what I ought to do about it?

I guess not...

Well it's very basic command stuff so I assumed maybe the error message would be generic.

It would seem to me that the error message gave you the solution right in it, "Use emitter.setMaxListeners() to increase limit"

Except I have not even a beginning clue what "Use emitter.setMaxListeners() to increase limit" means.
