UI grid memory leak issue

[BhagyashriJ]

I am using UI grid v4.0.2, where its mentioned memory leak issue is fixed. I have total 174MB data bind to grid. If I do page refresh then only first time its loading data. but When I am trying to call api to get data and bind to grid second time its crashing. Second time it should release memory but its not releasing , I can see previous memory references.

• Tried to reload state before calling api next time(as on page refresh its working first time)

• Tried cleaning all grid objects on $destroy and reset method before calling second time.

  delete $scope.gridApi;
  delete gridApi;
  delete $scope.gridData;

But its crashing second time.

Is there any solution on this ? Appreciate if anyone find this solutions.

@BhagyashriJ: So far my understanding in ui grid, memory object retaining is possible of several cases

1. Cell Template objects might lock with Events listeners
2. Directives inside the cell template locking sometimes if event or watches are locked
3. ng-if or ng-show or hide linking with global objects or rootScope possible to have leak

Really hard to archive this point clean in time,
So i try more record without cell templates, grid is destroying when switching with the routing,
if your are using large dataset make sure you have stored that in less no of object because it will multiply the object memory. Avoid to store the data in $scope object if already present in grid.data.

I have faced this issue when long usage with application, i have provided solution with the counter of routing, when Counter reach my limit i will call clear page (Blank page no angular). and return to same link. i can drop now the memory down 60 % to avoid hanging and slowness.

It is happening as well on the tutorial page itself.

Go to http://ui-grid.info/docs/#/tutorial/401_AllFeatures and click 'Refresh Data' load of times. You will see that the memory heap goes up and up and never releases any resources.

Any work around?

Thanks,
