Hi My client needed a server rebuild after a ransomware attack so I took the opportunity to upgrade from FB2.5 to FB3. My client application is Delphi using IBX components.
Now they are experiencing repeated crashes with an array of exceptions - the most common being "Error writing data to the connection" and "invalid transaction handle (expecting explicit transaction start)" mostly on select queries. The client is about 30 users accessing 6 different databases. The FB server also locks up (ie service still running but no response) about once a day (which never happened with v2.5 over years) which requires a service restart. Is it possible to downgrade a FB3 database back to FB2.5? (Googling suggests not as gbak seems version specific) I have googled but can find nothing on the "Error writing data to the connection error" - does that come from the client dll or the server? Thanks for any ideas. Tony
