Hi Roland,

Terminated abnormally is indication of the server crash, not database
corruption (though it can be some relation).
First of all, you need to look at UDFs you are using.
Did you migrate recently from 32 bit version, and one UDFs is 32 bit?
Did you add new UDFs recently?

Then, if UDF are Ok (or, better, no UDFs at all) try to reproduce crash
with metadata only backup.
If it constantly repeats, this can be sign of some internal bug in
Firebird. In this case you need to add bug into tracker.firebirdsql.org
with test case (zip and attach there metadata backup).

It's not stange - in 2.1+ Firebird allocates additional undefined pages
in the end of the database file for performance and safety reason.

Did you run Diagnose after that?
Though, since you was able to make backup, and problem at restore level,
I doubt that FBFirstAID will show anything.
