Memory leaks in Schedule

While using Schedule the heap size is constantly growing. When I navigate to a new date and new collection of events is loaded from the remote URL the previous collection of events is not released and still kept in memory.

I use React Schedule("@syncfusion/ej2-react-schedule": "19.4.52"). Events are loaded using remote data source:

dataSource: new DataManager({

     url: '/api/v1/appointments',

      adaptor: new SchedulerAdaptor()

}).

I attached screenshot from your demo (https://ej2.syncfusion.com/react/demos/?_ga=2.47615904.686433993.1658241303-1645642644.1594124282#/bootstrap4/schedule/remote-data ).

Is there a workaround to prevent the heap from growing while navigating between days?


Thanks in advance.

Hi Ivan Pohorilyi,


We are sorry for the inconvenience.


Due to some complexities, we could not include the fix for the issue “DataManager causes memory leak when we do multiple server side actions” as we updated. However, we will include the fix in our Volume 3 2022 release which is expected by the end of September 2022. Until then we appreciate your patience.

Hello guys,


any success with this issue? It's a bit annoying to get OutOfMemory exceptions every few hours
