End of communication file error ....for xmldom

Question

Hi,
Below is a procedure that i am executing.
I am using NOCOPY For the clob variable.
While executing the procedure for an xml value for clstring i am getting an error like
--end of communication channel.
The xml data is very big but not more that the size for clob.
procedure Prc_UpdateNodes(clString in out NOCOPY CLOB, nodename varchar2, nodeValue varchar2) is
        l_doc_node xmldom.DOMNode;
        l_xml_out varchar2(2000);
        begin
                  domDocument      := Fn_GetXmlDocument(clString);
               nodeList           := xmldom.getElementsByTagName(domDocument, nodename);
               intNoOfNode       := xmldom.getLength(nodeList);
               l_doc_node := xmldom.item(nodeList, 0);
               --xmldom.writetobuffer(l_doc_node, l_xml_out);
               PKS_DEBUG.PRC_DEBUG('CLOB IN PRC_UPDATE' || clString);
               for loopCount_int in 0.. intNoOfNode - 1  loop
                 node := XmlDom.item(nodeList, loopCount_int);
                    valueNode := XmlDom.getFirstChild(node);
                    --xmldom.writetobuffer(node, l_xml_out);
                    --This return value would be useful only in case of single record where in we could use the same after the insert operation is done
                    -- so that it could be used for the subsequent retrieval.
                    -- In case of multiple records update, this information remains of no use and doesnt have to be handled.
                    XmlDom.setNodeValue(valueNode,nodeValue);
                    --xmldom.writetobuffer(valueNode, l_xml_out);
               end loop;
               PKS_DEBUG.PRC_DEBUG('CLOB AFTER PRC_UPDATE' || clString);
               XmlDom.writeToClob(domDocument,clString);
               PKS_DEBUG.prc_debug('REMOVING BUFFER');
              PRC_REMOVE_BUFFER(clString);
               PKS_DEBUG.PRC_DEBUG('CLOB AFTER WRITITNG TO CLOB' || clString);
        end;The error occurs during the execution of the statement XmlDom.writeToClob(domDocument,clString);
Do i need the above statement as i am using NOCOPY For the CLOB variable.
Can anyone help me with this front..
Thanks.
