Error While returning CLOB back to Front End Application

Question

Hi All,
I have stored procedure which generate XML CLOB and returns CLOB back to front end application.
But when my CLOB exceeds some limit the front end application is not able get the CLOB.
Following is the error i am getting.
Procedure call to stored procedure
_len number;
l_buf VARCHAR2(32767);
v_ret_clob CLOB:=' ';
begin
Orcl_Proc_Ctrl_4_Xml.EXECUTE_CONTROL(v_clob,v_ret_clob);
l_len := dbms_lob.getlength(v_ret_clob);
dbms_output.put_line('the return size OF CLOB------> '||l_len);
dbms_lob.read(v_ret_clob, l_len, 1, l_buf);
virsa_dbms_output(l_buf,100);
end;
Error Output
the return size OF CLOB------> 113906
BEGIN test_oraact1019; END;
ERROR at line 1:
ORA-21560: argument 2 is null, invalid, or out of range
ORA-06512: at "SYS.DBMS_LOB", line 715
ORA-06512: at "APPS.TEST_ORAACT1019", line 16
ORA-06512: at line 1
I am able to get the Size of CLOB but when i try give back to Front end application it is not properly passing CLOB.
Any help on this.
Thanks in advance
Prashant
