Me and my friends started playing on a minecraft vanilla server without any mods. I believe we're using the dirt plan, and it seemed like the server was running fine earlier today. But suddenly it started crashing. We've only been playing for a bit, and the most we did was travel a bit and dig. We're not sure if it has anything to do with the server being at 100% memory. The world file and all other files don't seem that big, and it doesn't look like the server console is complaining about anything, so we're not sure why it's crashing every few minutes with only 1 or 2 players on the server. Hoping someone could help with this. We'd like to play without disconnecting every few minutes.
