Asp.net paging crashing on chrome

I have a timer control on my page and an image handler which is set on every timer refresh. After about two minutes of running my page the page crashes on chrome with the "Aw Snap message". Can anybody help me out ??

JS Code.

    var t
    function set_coordinates_up(event) {
        //Get final co-ordinates
        var pos_x = event.offsetX ? (event.offsetX) : event.pageX - document.getElementById("divCar").offsetLeft;
        var pos_y = event.offsetY ? (event.offsetY) : event.pageY - document.getElementById("divCar").offsetTop;
        var hdf = d开发者_运维问答ocument.getElementById('HiddenField1')


        //Store event information in hidden feild
        if (hdf != null) hdf.value = t + " " + pos_x + " " + pos_y;

    }
    function set_coordinates_down(event) {
        //Get initial co-ordinates
        var pos_x = event.offsetX ? (event.offsetX) : event.pageX - document.getElementById("divCar").offsetLeft;
        var pos_y = event.offsetY ? (event.offsetY) : event.pageY - document.getElementById("divCar").offsetTop;
        t = pos_x + " " + pos_y
    }

check if your tab is leaking memory for some reason by opening up Chromes Task manager... probable reasons would be an infinite loop somewhere.

Chrome pages usually crash (Snap!) when there is low memory on the system. I would worry about that too.. Make sure you dont have many other processes running either.

Keep us updated.
