Since FMS 12 to FMS 14 I have random data losses when updating a solution with exported records from Backups. A hosted file contains for example 10.000 records, opening the backup file also shows 10.000 records - but I can only move up to record 8.235 and only export 8.235. Exporting from the host will export all 10.000 records and display each record beyond 8.235. The backups are "checked" and the server reports no error.
Repairing the backup-file will solve that - the repaired file works fine.
Making a clone, importing all data in the clone solved all kind of internal problems in the past, but in this case it still leads again to the error weeks or months later.
Any idea what might happen and how to check that? Im am working mainly with OS-X for the server and keep fms and os-x up to date - with a secure delay ... It happens in different configurations with different customers - FMS 12 to 14, OS-X 10.9 to 10.11.
