Repeated instances of duplicated auto-enter serial values
Operating system version
Description of the issue
Since we upgraded form FMS 11 to FMS 13 in January, we've seen a sharp increase of duplicated auto-enter serial values. Two concurrent users create a record in the same table simultaneously, and both records are assigned the same serial value. We don't want to set the field to require unique values because we don't want users to have to handle that error when it occurs, and we don't want to interrupt the complicated scripts surrounding creation of records in these tables. There is another serial field on this same table, also not requiring unique values, that never has this issue.
Steps to reproduce the problem
Two records are created simultaneously in a table with auto-enter serial values for a field.
Two records created in this table concurrently will have different values for this field.
Two records end up with the same value.
One of the records must be created again, and one of the duplicates must be deleted.
