IE8 Jquery settimeout crash every 3-4 days

IE8 Jquery settimeout crash every 3-4 days

I have this html page running on IE8 and it crashes every 3-4 days. Is it something wrong with the use of settimeout here? I also used proxy and it did not help. But it can run on Firefox with no issue.

var me = {  
                 _panelRotationTimeout
 : null ,
                _showPanel
 : function ( index ) {
               
//Reset index
              
if ( index > 10000 )

          

{
            index
 = 0 ;
          
}
            $
 ( "div" ). text ( "CXY:" + index );
               
// set timer when to switch to next panel
           
var that = this ;
           
var ind = index ;
              
this . _panelRotationTimeout = setTimeout ( function () {
                   
if ( that && that . _showPanel ) {
                        that
 . _showPanel ( ind + 1 );
                   
}
               
}, 1000 );
            $
 ( "h1" ). text ( "CXY=done:" + index );
       
}
   
};
    me
 . _showPanel ( 1 );
