Geonis Interlis Export - ORA-24550: signal received: Unhandled exception: Code=e0434352 Flags=1

When exporting Interlis/LK Map FME just stopped working. Log file didn't contain any further information about the cause.

I had done an export successfully earlier with a project from the test database. Using the production database FME crashed.

The only difference I noticed was that the test project used an owner-connection to Oracle, the production project a editor-connection.

To get more information about the cause of the issue I ran the FME workbench in Windows command line - that's where I got the more detailed error message:

I don't really know what the error message is about. But when I run the export using the owner-connection it finishes successfully.

ArcMap 10.5.1, Geonis 2017.0, FME 2016, Oracle 11.2
