I did.

You are right. We are more and more thinking about using 1.5.4,
perhaps is the solution. Anyway, it is worth trying. But you know,
we have allways been rather conservative with software - we are
still using v0.65 of the busybox for example, and kernel 2.4.21. It
is not just a matter of updating one DB server, but many thousands,
so we need a good raison for this.

Clients do not access to the database. They access to a service we
have written. This is a multithreaded service; one (and only one)
thread is connected (only one connection) to the database. We use
SQLAPI (from www.sqlapi.com), a set of C++ classes encapsulating the
firebird API.
