jQuery Ajax - After 2mins net::ERR_INSUFFICIENT_RESOURCES

This is the code below,

The Page loads fine with the dayofweek and hourofday functions. But shortly after the browser (chrome) freezes up and gives the error : net::ERR_INSUFFICIENT_RESOURCES and referrs to the Jquery library and my hourofday.js script.

After a few mins it starts getting errors like crazy and it freezes. I cant even reload the page. And the resoure

here is the script:

function dayofweek(){
    $.ajax({
        url: "dayofweek.php",
        type: "POST",
        dataType: "xml",
        success: function (xml){
        var day = $(xml).find('day').first().text();
        $("#dayofweek").html(day);

    },
         error: function (xhr, status) {


    },
         complete: function (xhr, status) {
    }
 });
}

function hourofday(){
    $.ajax({
        url: "hourofday.php",
        type: "POST",
        dataType: "xml",
        success: function (xml){
        var response = $(xml).find('response').first().text();
        $("#hourofday").html(response);
    },
        error: function (xhr, status) {


  },
        complete: function (xhr, status) {
   }

 });
setInterval(dayofweek, 6000); 
setInterval(hourofday, 6000);
}
