What is your exact Oracle version (all 4 numbers please, like 11.2.0.3)?

I believe the issue is the second:
dbms_output.put_line ('T '||lv_table7);

There is a string concatenation in there that is probably causing the issue.

Try just the clob:
dbms_output.put_line (lv_table7);

i tried without the string concatenation, it did not work, so instead parsed out the text in 30K chunks...and that worked..
