I can't figure out and answer to this so I'm hoping that maybe someone else can. I use minecraft forge for mods, and I have a decent gaming computer that can support the game well. Normally when I play mc on forge my game will only be using around 30% of the memory I allocated to it (4gb allocated out of 16gb). But randomly my memory usage will start reaching max (it randomly spikes from 30% usage to 100%) and it stays there. Then my game will proceed to keep freezing and unfreezing, and it won't stop until I restart my game. It only happens in forge, no where else.
