Memory Leak when call push.on('registration'. so Push Plugin register called not called

[kntmrkm]

I have already confirmed that push notification works in my env.
This means my code is almost correct.

But, sometimes application crash with memory leak.
it occurs randomly.

Log without memory leak

2016-03-23 14:01:13.224 App[8280:3054328] Apache Cordova native platform version 4.0.1 is starting.
2016-03-23 14:01:13.338 App[8280:3054328] Ionic Core: plugins are ready
2016-03-23 14:01:13.708 App[8276:3053868] initializePushNotification
2016-03-23 14:01:13.732 App[8276:3053914] **Push Plugin register called**

line 4 is correct behavior.

And next build (I validate this with xcode build and real device.)

I'm using ionic framework.

Gulp local:   Local version 3.9.0

Node Version: v5.3.0
Xcode version: Xcode 7.2.1 Build version 7C1002

• Apache cordova ios version is 4.0.1
• iOS version is 9.2.1

My code is

function initializePushNotification() {
  console.log('initializePushNotification');

  // PUSH Notificaiton
  try {
    var push = PushNotification.init({
      android: {
        senderID: "XXX"
      },
      ios: {
        alert: "true",
        badge: "true",
        sound: "true"
      },
      windows: {}
    });

  } catch(e) {
    console.log(e);
  }

  try {
    push.off('registration', function(data) {});
    push.off('notification', function(data) {});
    push.off('error', function(data) {});

    push.on('registration', function(data) {
      // Push Plugin register called
      console.log('PushNotification registration: ' + data.registrationId);
    });
  } catch(e) {
    console.log(e);
  }
}

$ionicPlatform.ready(function() {
  // Hide the accessory bar by default (remove this to show the accessory bar above the keyboard for form inputs)
  if (window.cordova && window.cordova.plugins && window.cordova.plugins.Keyboard) {
    cordova.plugins.Keyboard.hideKeyboardAccessoryBar(false);
  }
  if (window.StatusBar) {
    StatusBar.styleDefault();
  }

  initializePushNotification();
});

I solved this issue.

But I did not found cause of memory leak.

I have upgrade cordova-ios version from 4.0.1 to 4.1.0.

Then, there is no problem.

I had the same issue and I don't know the cause, if anyone knows please advise.
