When I synchronise with another database, partial imports of Equipment Modules happen to give errors on a more or less random basis.

The Error message is:

1: INFORMATION:  '_PUMP_EQM'  refers to '__5C33551D_012B3C55__' which is being updated or deleted
1: WARNING: DATABASE INTERNAL ERROR
2: WARNING: An Objectivity database error occurred
3: WARNING: Objectivity message
** System Error #4618: ooHandle(ooFDObj)::open(): Storage Manager: Journal file
                       is version 0 instead of 20. It must have been created by
                       an incompatible version of Objectivity/DB (102327)
4: WARNING: Operation on database map failed
5: WARNING: IMPORT ERROR: IMPORT of FUNCTION_BLOCK_DEFINITION with key  NAME='__5C335539_012BABCA__', CATEGORY=''  FAILED at  line:421 column:2. This could cause other serious import errors for related items in this file. Import is now resuming at the next item in the file.

This error message may happen on other parts of the import (fhx file) with a second of third import.

I (extended) cleaned the database on a regular basis.

The origin of the import is at the same version as the target machine: Version: 13.3.1

What could solve this phenomenon?
