Current version doesn't seem to work too well... I need just to connect to some hub and LinuxDC++ starts to eat up memory and CPU... I closed it at 500megabytes, which took only like minute to get there, wnd I didn't even relaly done anythign yet.
Are you sure you're not trying to hash a large amount of data at the same time? Hashing is a cpu and memory intensive process. Try starting with a new profile to see if it fixes the problem.
