Hey guys,

I'm having issues with my MC server, it's lagging and keeps crashing, I hope you can help me out of my misery!

Here are some infos on the server:

Vanilla Minecraft 1.15.2

running on V-Server with 4 Vcores and 8GB RAM

running on Ubuntu 18.04.3 LTS

with no other significant servers/applications running



View Distance 12

Survival Mode



Maximum of 4 players

World is around 1GB in size

No gigantic monster farms or similar

One time I accidentally run the '/bossbar' command without any parameters. That created a bar at the top, but also introduced lag. Since then, even after I removed the bossbar the server is still laggy. Ticks are taking way too long.

[10:14:40] [Server thread/WARN]: Can't keep up! Is the server overloaded? Running ...ms or ... ticks behind

[10:18:48] [Server Watchdog/FATAL]: A single server tick took 60.00 seconds (should be max 0.05)

[10:18:48] [Server Watchdog/FATAL]: Considering it to be crashed, server will forcibly shutdown.

Here's my troubleshooting:

• Running a debug session
• Noticed in the log:

[17:59:45] [Server thread/WARN]: Something's taking too long! 'root.tick.levels.world minecraft:overworld.tick.entities.regular' took aprox 177.425314 ms




• That sounds like we do have too many entities like animals, but as said, no gigantic farms or anything
• What is an okay entity count I can check in the debug menu?

• Server is lagging no matter where you are
• No corrupted chunk or similar

• Server doesn't have enough power?

• I downloaded the map and ran it as a single player map on a powerful machine, still getting warnings about ticks taking too long

• Map to big?
• We did explore quite a bit and the map is 1GB in size, but the server is only handling the world where a player is present

• World file broken?
• I read that MCEdit or similar can fix corrupted chunks, but as said, the problem isn't specific to a chunk or location

Don't know where else to look, help would be much appreciated!

Thank you,

best wishes,

Leo
