Checked. No dangling connections in the transaction pool after backup restore. 
Then when the ~connection shutdown~ error state is reached only 3.0 connections 
are in the pool.

If i wasn't clear I can't create any connection in that state. Not even create 
a new Database and connect to that. Any connection will throw a ~connection 
shutdown~ Exception after that state is reached.
It is not dependent to a certain database. Feels more like the hole embedded 
Firebird client is in a shutdown state then :(

I call FbConnection.ClearPool before backup. So there shouldn't be any 2.5 
connections to that database still hanging around. 
The backup restore I do is inplace. I have replaced the fdb database in its 
original location (2.5 before a 3.0 version afterwards). I assume if I had 
2.5er connections still in the pool that won't be allowed since there would be 
open handles to the database and I couldn't replace the file then? 

I will check if clearing the pool when I'm running into the ~ connection 
shutdown~ error state helps. But I doubt that this problem has something to do 
with the connection pool.

Are you sure. Isn't just cleaning the pool for that connection enough?
