I started a new world with my old mod pack after some hiatus. There I was using DH 2.3.3 and after couple hours of gameplay, minecraft process reached 30GB of private bytes and lead to crash of whole PC. I assume this was problem on DH side because when I removed it, minecraft process never too that much memory.
For the latest DH version, was the memory leak fixed?
But it might be as well incompatibility with other mod in my pack. I don't seem to have any mod from this list: No Access
