Cause
This error occurs in two cases.
When a transaction has created an object in a partitioned database file and this overlaps with an existing transaction that has added one or more new partitions to the file, the transaction creating the object will encounter an exception with this error.
When a transaction creating a new partition overlaps with an existing transaction that has added one or more new partitions to the file, the second create partition action will encounter an exception with this error.
Action
Implement logic in your application or work flow to serialize these operations.
