Oracle : Ошибка ORA-10750

"test rollback segment blksize guessing for index array insert"
*Action: set this event only under the supervision of Oracle development
*Comment: causes internal error to be raised if a transaction
repeatedly (100 times) fails to bind to a rollback segment
because block size is too small. (Default behaviour is to
silently assume the minimum database block size possible after
that many failures). Enable this event only during testing.
