At the second costumer site i've installed Firebird 1.5.2RC1 and Jaybird 1.5.4.
But now the error happens every day.
It's not reproducable, because everytime it happens in another db-operation, but after that the connection is not usable anymore and the connection pool returns this invalid connection everytime.
