I dont work that much with services, but maybe that, when you send shuttdown signal to Firebird, ServiceB shutting down are not yet finalized. If that is true, you need something to wait till properly shutting down of ServiceB to then shutt down Firebird Service.

I am not sure, but seems that is the problem.
