I did not know what platform or whatever to put this under but it is a problem that i have. So i have currently tried to play pixelmon, a usually low memory runned mod, well so i thought. i had a computer custom made with a GTX 1060 Graphics Card, 16 Gig ram, and an intel I5-7400 and when i go to run pixelmon and play on the server, it says that the minecraft im playing has run out of memory and they are trying to free up space. i was very shocked to know that but idk why that would be, i usually dont run games on more that 5-6 gigs of ram, but its saying that ive ran out of memory so i dont know how to fix it, if you can help me with this problem that would be greatly appreciated.
