Not enough information here.

How do the applications connect? (tcp/ip, netbeui, etc.)

What model of Firebird? (SS, Classic, embedded)

Are all of the clients using the right client library? Must be the one
that comes with the Fb 1.5.3 kit, i.e. matching build numbers.

Are you using a beta (RC) version of Firebird? The full release came out
before Christmas.

Does each thread use its own complete structure of explicit TIB_Session.
TIB_Connection, transactions, statement objects, etc.? (Essential! You
can't share any TIB_Sessions across threads.)

Is Remote Desktop being used?

Are any applications using events without any (or sufficient) ports opened
in the firewall?

And so on...
