With 2.5, do you mean 2.5.0 or a newer version (eg 2.5.5)? I believe
there were some memory leaks fixed since the initial 2.5.

Is it easily reproducible? If so could you send me the program and
database so I could try it myself?

Could you also try with Jaybird 2.2.8 or earlier to rule out regression?

Does your program depend on auto-commit? If so try switching to explicit
transactions and see if that improves memory usage.
