I have a asp.net web application in which a JavaScript call is made to a web service which is written in VB.  The web service accesses a data set which is in a session variable and returns it as XML.  For most users the returned XML is a few thousand characters but for some it can be over 800,000.  The error in the title occurs when the XML is somewhere over 55,000 characters.  The error occurs in the depths of the auto generated JavaScript so I haven't had much luck debugging it however it is apparent that there is a default limit on the size of the string returned by web services.  I searched the web and found some things about disabling SOAP and setting the JSON size limit in web.config but that didn't work for me.  The code for the JavaScript and the web service are below.  Any suggestions would be greatly appreciated.
function PopulateRecordsFor() 
{
    try
    {
    RecordsForService.PopulateList(PopulateRecordsForCallBack);
    }
    catch (e) 
    {
        alert("Alert 1" + e.description);
    }
}

function PopulateRecordsForCallBack(result)
{
    try {
        var xmlDoc = new ActiveXObject("Microsoft.XMLDOM");
        xmlDoc.async = "false";
        xmlDoc.loadXML(result);
        var xmlname, xmlid
        var findNodes1 = xmlDoc.getElementsByTagName("Name");
        var ddl = $get("ctl00_ddlRecordsFor");
        for (i = 0; i < findNodes1.length; i++) {
            xmlname = xmlDoc.getElementsByTagName("Name")[i].childNodes[0].nodeValue;
            xmlid = xmlDoc.getElementsByTagName("FileNumber")[i].childNodes[0].nodeValue;
            var objOption = document.createElement("option");
            objOption.value = xmlid;
            objOption.text = xmlname;
            ddl.add(objOption);
        }
    }
    catch (e) 
    {
        alert("Alert 2" + e.description);
    }
}
