Daniel this is obvious... if I have not TIB_Session for each connection the
program would
crash also on single processor machines.
My problem now is on a simple form with two connections and a datapump
that doesn't work on the Xeon 2.8 with HT enabled
but that works if I run it from another machine using the Xeon only as a
Database Server.
