Execution does not end even after all records updated..

Question

Hi,
I have plsql code like :
declare
begin
for x in ( select .......) loop -- about 4000 times
for y in ( select ............) loop -- about 50 times
end loop;
-- some code goes here to manipulate clob data
-- like creating free temp clobs - use - then free them
-- Update statement that update some table using clob values.
insert into tablex values(sysdate);
commit;
end loop;
end;
Here I can monitor from other window howmany records are inserted into tablex and howmany updated in update statement by...
select count(1) from tablex;
After 50 mins i can see that all records are updated but...
plsql code does not end its execution it continues even after all records are updated..untill i have to kill the session or let be run for long time.. :(
I can not understand why this it is not ending execution..
What could be the problem ...

Hi,
Here it is.....
declare
v_text_data TableA.text_data%type;
v_clob clob;
type dummyclob_t is table of clob index by binary_integer;
dummyclob dummyclob_t;
v_str varchar2(255) := 'ddfsajfdkeiueimnrmrrttrtr;trtkltwjkltjiu4i5u43iou43i5u4io54urnmlqwmreqwnrewmnrewmreqwnm,rewqnrewqrewqljlkj';
begin
select data bulk collect into dummyclob from sfdl_clob; -- five rows containing clob data upto 1MB
for x in (select object_id
from TableA
where object_type = 'STDTEXT' ) loop
dbms_lob.createtemporary(v_text_data,TRUE);
for y in (select '<IMG "MFI_7579(@CONTROL=' || ref_id || ',REF_ID=' || ref_id || ').@UDV">' temp_data
from TableB
where object_id = x.object_id) loop
v_text_data := v_text_data ||
case
when trunc(dbms_random.value(0,7)) = 0
then chr(10)
else v_str
end ||
y.temp_data;
end loop;
select text_data into v_clob from TableA where object_id = x.object_id for update;
if v_text_data is not null then
dbms_lob.append(v_clob,v_text_data);
end if;
dbms_lob.append(v_clob,dummyclob(trunc(dbms_random.value(1, 6))));
dbms_lob.freetemporary(v_text_data);
insert into xyz values (sysdate);
commit;
end loop;
end;
Thanks for your time..:)
