See the values for maxRequestLength value of httpRunTime in web.config. Try changing it to a bigger number.

It seems like HTTP web request size is exceeding in your case.

The 4MB default is set in machine.config, but you can override it in you web.config. For instance, to expand the upload limit to 20MB, you'd do this:

<system.web>
  <httpRuntime executionTimeout="240" maxRequestLength="20480" />
</system.web>

Edit

For IIS7 and above, you also need to add the lines below:

 <system.webServer>
   <security>
      <requestFiltering>
         <requestLimits maxAllowedContentLength="1073741824" />
      </requestFiltering>
   </security>
 </system.webServer>

Note: maxAllowedContentLength is measured in bytes

Try to use DataSet ReadXml(XmlReader) method.

To create XmlReader

FileStream st = File.Open(@"filepath", FileMode.Open);
XmlReader reader = XmlReader.Create(st);  
DataSet ds = new DataSet();  
ds.ReadXml(reader);
