My 1.8.9 world is currently ~70gb. Whenever the world saves, either the server freezes for half a minute or it times out almost all players. Could this have to do with the fact that it is constantly using up 100% of the ram (20gb) I allocate it?
Here’s what it gives me:
[18:13:31] [User Authenticator #1017/INFO]: UUID of player censored is a4s34d0-c988-48c5-32ea-e2b46sijcenob4
[18:13:31] [User Authenticator #1018/INFO]: UUID of player censored is ce4se4c-17dd-46f2-a8d2-68685725941d
for almost every player on server
[18:14:04] [Server thread/WARN]: Can’t keep up! Did the system time change, or is the server overloaded? Running 33662ms behind, skipping 673 tick(s)
Also this being spammed
[19:18:38] [Server thread/WARN]: handleDisconnection() called twice
Update: Changing the save intervals to 10 seconds seems to solve it, but now it’ll have random episodes of timing out 3-5 times in a row. Not sure what’s going on
Update: Timings Report link
It appears that block update and chunk populate are the culprit of the time outs… But most of my world is already pre-genned and the timeouts even happen with less than 10 players on, none exploring.
