Subject Re: [firebird-support] Using FB 3.04 with Delphi 10.2

Sounds to me you are using local access to the database, either in the
IDE or when running the program (or both).
Does the connection params contain a hostname or ipnr? If not, it's
probably a local connection. In that case only one process can connect
to the db. The IDE (connection component) may be stay connected, so when
running the program you get this error.
