[1.12.2] Server Randomly Freezes


Recommended Posts

Greetings, i have a little Problem and dunno how to solve it.

Iam Hosting a small modded Minecraftserver for me and some friends. Now the Server seems to randomly freeze.
Every Player is timing out, server itself dont seems to crash. There are also no log entrys and no crash logs. When i open the screen session, the server looks fine but when i enter something like save-all, no response.

All i can do then is to force it stop and restart it. That drives me a bit crazy xD

I hope someone can help me to figure out whats the problem.



Minecraft Version: 1.12.2
Forge Version: forge-1.12.2-


Server Specs:
16gb DDR4 RAM
AMD Ryzen 5 2400G


If there is some more specific things needed to know, please tell me.

Thx in advance

like i already wrote, there is nothing in the log. its liek the server worked normal. When it stops (freeze) also no log things appear, cause it doesnt write any log. But i added it anyway. it happened at the end of the log ofc.

i try to but the site wont let me add the debug log (70.5mb) and zipped also wont work. it says error -200. file is also to large for pastebin.


edit: do you mind if i add it to gdrive? ( https://drive.google.com/drive/folders/1V3RjnaRpUUXaXc65vjpLSKw7tmfC7A2z?usp=sharing )


Server Stopping ad end of debug log is cause i killed screen session (ctrl+c)

One thing I can tell you is that "Playerlogger" is completely spamming the log file (> 500 messages every second). Try removing it.

disabled it now. Will take a look onto and tell you then if it resolved the problem or not. Thx much.

thats kinda freaky. changed the BiomeBaseID in core.cfg to 250 now. well see if thats the isse. Will check it a while again xD

The issue still exists. It almost always seems to happen when server resumes from hibernation, but also randomly sometimes on run. I updated the log files:

no one? :(

My custom server I run for me and my friends is doing this same thing, randomly freezes up and drops all my friends out, I have to hard kill the server to bring it back sometimes, maybe we can compare mods to see what we are both using to help us narrow it down? It sucks because I to am not getting any logs.

I think, windows is freezing the task(java), because its idle. Im not 100% sure and wont explain why it happens while you're on the server, but its worth to research it.

Im doing it aswell and inform you of any updates
