MaxListenersExceededWarning in sails js

I am using sails js but encountered with this error

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

is it a socket issue or something else ?

Solution

  • By default nodejs is set to allow 10 listeners at any event. If you want to change it you can use

    setMaxListeners(n) //n be the number of listeners

    Plus you can use node --trace-warning app.js to exactly get to the point which is generating this exception
