Thanks Karol/Dmitry

I will install the latest snapshot to see if it changes. (This is a big shock after FB2.x has been running rock solid for about 20 years)

Is it possible to downgrade a v3 database back to v2.5 - google suggests "maybe" but my tests all fail with gbak giving errors about backup version or ods

Thanks
Tony

 

 

Hi,

 

as Dmitry say problems can be already solved in snapshot build

e.g. http://tracker.firebirdsql.org/browse/CORE-5307 can be same as your problems –

use napshot build from

http://www.firebirdsql.org/en/snapshot-builds/

 

regards,

Karol Bieniaszewski

It's worth trying a v3.0.1 snapshot before considering downgrade. It may
have these issue fixed already.
