Of course, just saying it's leaking memory doesn't help much . . . is there any particular point at which you notice GalCiv II leaking memory?
@Greenreaper - mentioned on a couple of other threads, but from my observations the biggest culprit for the memory leak is the planetary invasion process. Can play for hours without a problem and mem usage stable @ ~600Mb, then embark on a war which involves lots of invasions it steadily increases up to 1.5Gb before hitting an "out of memory" error on saving.
