some deleted series are still listed as records in the OAI interface (“ListRecords”).
There are no entries for these series in the tables series or series_settings, but they are listed in data_object_tombstones.
Since the series cannot be found when clicking on “Records”, an HTTP ERROR 500 occurs.
The OMP installation was upgraded from OMP 1.2 . Is this still a bug in the code or is it enough to delete the entries from the tombstone tables? Are there possible side effects when deleting entries from the tombstone tables?
