datatable.ajax.reload() with setInterval 导致页面崩溃，如何避免 memory 泄漏？

Question

Here's my code, Ajax request for dataTable return 2000 rows of data. I want to update datatable every 2 seconds with new data. It is requesting 2000 rows of data every 2 seconds. But with setInterval the page crashes after 10-12 minutes because of memory error. Is there any way to clear the memory without using location.reload()

var dataTable = $('#tblDemo').DataTable({
    "ajax": {
        "serverSide": true,
        url: "abc.php?data=getSomeData",
        type: "POST",
        data: {}
    },
    "pageLength": 15
});

setInterval(function() {
    dataTable.ajax.reload(null, false);
}, 2000);

use "destroy" option to destroy old data.
