This error is usually caused by a DDL statement that fires a system triggerthat
tries to modify the same object. It can also happen when an attempt is made to
perform more than one DDL operation on a queue table in the same transaction
without issuing a commit between operations. Action: Do not create systemtriggers that might modify an already modified
object. Also, do not specify more than one DDL operation on a queue table inthe
same transaction.
