Javascript/Jquery - too much recursion

Question

I am working on a script that scrolls table data in a continuous loop. The issue I have is, I keep getting the following error:

"too much recursion".

Does anyone know how I can use the script without this error happening?

$.fn.confScrollUp=function(){

var self=this,conf=self.children()
setInterval(function(){
    conf.slice(30).hide()
    conf.filter(':hidden').eq(0).slideDown()
    conf.eq(0).slideUp(4000, "linear",function(){
        $(this).appendTo(self)
        conf=self.children()
    })
},1)
return this;
}


$(function(){
    $('section').confScrollUp()
})

There is not user interaction, its just for displaying data.

Are you sure you want that setInterval firing once every millisecond? — Andy

@Andy Hi to be honest, no.I just need the scroll to work but I am not sure what to change. — DCJones

Can you add it to a jsfiddle or something so we can see it not working? — Andy

@Andy Hi, jsfiddle.net/Blackbox/dsm3dg55/10 I have changed the code to scroll faster but its too fast. — DCJones

This seems to work error-free if you increase the setInterval interval. Here I've chosen 100 to go along with the increase in the slider value to 4000.

$.fn.infiniteScrollUp=function(){
    var self=this,conf=self.children()
    setInterval(function(){
        conf.slice(10).hide();
      conf.filter(':hidden').eq(0).slideDown()
      conf.eq(0).slideUp(4000, "linear",function(){
        $(this).appendTo(self);
        conf=self.children();
      });
    },100)
    return this;
}
