On creation and even on deletion of any document I get a duplicate key exception in the postgresql-database:
### Error updating database. Cause: org.postgresql.util.PSQLException: ERROR: duplicate key violated
2 calls (apparently retrying):
insert into alf_content_url (id, content_url, content_url_short, content_url_crc, content_size, orphan_time)
values (?, ?, ?, ?, ?, ?)
The documents are being created without errors in Alfresco (due to retrying transaction helper) but where do these exceptions come from?
Thank you very much in advance for some hints.
