@dyiing I allocated 12GB of ram and the problem persists.
Logs are here.

@dyiing How much RAM should I allocate? I noticed it happens ONLY when I load chunks now, I sometime load chunks accidently and it crashes.

This seems to happen randomly but not too long after I load up a server. I will be running around a bit in loaded chunks, not loading more, and my entire game crashes.

I know XRay doesn't have any problems because it happens without it.
This is a technic pack called "Pokecentral"

Does 1.12.2 have Seed Cracking? Is there anywhere 1.12.2 has seed cracking?
I know it has seeds, just cannot find any seed crackers anywhere and it doesn't seem like the server is running paper or spiggot.
