I'm having an issue with my Minecraft Paper 1.21.11 server hosted on MCServerHost. The server keeps shutting down and restarting automatically after around 10–15 minutes, even when there are only a few players online or sometimes when nobody is online at all.
I checked the console logs and I don't see any Java errors, exceptions, or crash reports. Instead, the logs show:
[INFO]: Stopping the server [INFO]: Stopping server
After that, the server saves all worlds normally, goes offline, and then MCServerHost starts it again automatically.
Server details:
Paper 1.21.11 Java 21 4 GB RAM Plugins: EssentialsX, LuckPerms, Vault, ViaVersion, ViaBackwards, ProtocolLib, LifeStealZ, SkinsRestorer, SuperVanish, OnePlayerSleep, JustTPA, SpawnProtection, MaceControl, DisablePortal, etc.
I have already removed plugins such as Orebfuscator, Themis, LagFixer, MCServerHost plugin, and ClearLagTimer, but the issue still happens.
Could someone please help me determine whether this is caused by a plugin, a scheduled restart, a host-side issue, or something else? I can provide the full startup and shutdown logs if needed.
Thank you! 🙏
