Hello,

This is a database corruption, most likely caused by bad RAM.
Another reason could be accessing Firebird database with wrong version
of engine (InterBase? old Firebird?).

Download free FBFirstAID version, check your database and send log for
free investigation to our support team: support at ib-aid.com.com
We'll check it.

Regards,
