ALthough KVS works like maps, the data is actually stored in an internal SQLite database after the data is serialized. You exceeded the cusrsor limit of 2048 KB
If you search for this: 'Cursor window allocation of 2048 kb failed.', you will find many postss. One of them similar to yours is this:

keyvaluestore problem

Hello I am using kvs (not v2 ) . I am getting an error of : android.database.CursorWindowAllocationException: Cursor window allocation of 2048 kb failed. # Open Cursors=406 (# cursors opened by this proc=406) full msg is here : Error occurred on line: 81 (KeyValueStore)...

You don't need me to tell you, but the title of the thread is really bad and non descriptive; it is not too helpful to the community.

I am not using cursor. Each 2 seconds i am writing new value to KeyValueStore. For example UserOnline = True or UserOnline = false but Perhaps cannot override.

Private Sub WriteValue(ValueName As String, Value As Object)
    KVS.Put(ValueName , Value )
End Sub

And when i need a value i am calling this sub

Private Sub ReadValue(ValueName As String) As Object
    Dim Value As Object = KVS.Get(ValueName )
    Return Value 
End Sub

I am writing to KeyValueStore, string values too for example UserID= "xxxxxxxxxxxxxxxx" and etc.
