So I've been running my own little SMP for a bit. It's a vanilla server and has been working fine until now. I can start up the server, join the server, and it starts loading the world. Then, about 15 seconds later, it kicks me and starts the shutdown timer. Here's the server log:

The server runs on 1.12.2 with 1200 MB of RAM. I also recently built a cactus farm and set the random tick speed to 10, not sure if that would be enough to crash the server though.
