Subject Error 335544528 in classic mode and multiple users
I have a web server suing Firebird. I installed it using Classic mode because it seems more robust.
Usually, databases have between 1 to 3 users concurrently as maximum. However, there are 50 databases and eventually many users could be using their database.

When I open the database, it works fine. Then, if I open the same database from another client , I get ISC ERROR 335544528, shutdown.

Is it related with Classic mode? I understand that Classic mode creates a new process for each client, but does it mean that the same database cannot be shared by 2 clients?

Thank you
