Thanks for your input.

We managed to get the DB upgraded to 3.0 (removed all charset ASCII definitions on fields while on 2.54, then backup the DB and restored it on 3.0, and it all worked). Now on the flip side, the performance sucks, it is worst than with FB 2.54, and when looking at the task manager on windows it appears only one processor it doing the job, as if the code was not SMP enabled.... very strange. We will leave 3.0 for testing at the moment, and continue to use 2.54 in production, in the meantime we will play with 3.0 and try to figure out what is it we are doing wrong.

Cheers,

Fabian
