DB doesn't like very big numbers. In settings you get overflow error in Species inviduals and starting energy, waste treshold, corpse decay perioid, every setting in population control and league rounds if you put value above 32767. Also, if you pute insanely large (several millions or hundreds of millions) in mutation oscillation frequency, nrg/round or in nrg management window sun up/down if-box, you get the same error. Otherwise settings seems to handle big numbers.
