Subject 335544344, file used by another process
Author Petter Holmström

One of my customers have this problem: When the login to the database
for the first time using my program, everything works well. If they
then logout and login again as another user, they receive this error
335544344 Cannot access the file because it's being used by another

If they restart the client program, everything works fine.
This error does not show up when connecting to the database with
IBConsole, nor does it show up on my internal development test

I'm using FireBird databases.

Any ides what this problem could be due to?
