That is the difference between a multi-billion dollar company with
dedicated teams of testers, and a small, underfunded, open source
project. Welcome to the open-source world, where the community is
expected to lift part of that burden.

And yes, you can have some expectation of quality, but all too often
people only start to really test when the first official release is done.

It depends. We can't possibly tell from the few details you have provided.

I strongly recommend creating automated tests. It removes the drudgery
from testing, and it is great to flush out regressions.

If it happens with a lot of connections, it sounds more like a race
condition (either in Firebird or in your software), or possibly wrong
use of transaction isolation levels.

What Firebird model did you use with 2.5, and what model do you use now
(SuperServer, SuperClassic or Classic)?
