Seema, It looks like the user tried to cancel the operation. ORA-01013. after they started the truncate. Could be it caused the insanity and crashed the system. That might be why you never saw it before. Try to create the same failure on a test system and see if the cancel causes a crash. ROR mª¿ªm
