Hi folks,

We've got a problem to restore databases on one of our customers server.
The error is something like

gbak: restoring index RDB$FOREIGN820
gbak: restoring index RDB$FOREIGN740
gbak: restoring index RDB$FOREIGN747
gbak: restoring index IXAUFTRVERLADUNG
gbak: restoring data for table TBLAUFTRAG
gbak: 10000 records restored
gbak: adjusting an invalid decompression length from 38 to 5
gbak: ERROR: validation error for column WAEHRUNGIDWNN, value "***
null ***"
gbak: ERROR: warning -- record could not be restored
gbak: Exiting before completion due to errors

The error varies a bit (different positions) depending on the backup
file.
But using the same backup file always produces the same error at the
same position.

If the restore runs on a different machine everything seems to be OK.

The backups were also created on different machines.

The machine was checked several times by hardware specialists (some
Siemens guys, because it's a Siemens computer).
No problems were detected. And other applications running on that
server are just fine.
The harddisks were replaced without any effect concerning this problem.

The problem occurs using firebird 1.0.2 and 1.5.2

In the meantime the customer temporarily uses a different server. But
we (they) are
of course highly interested in what could be the reason for this.

Any idea?
