I have issues with:
[Server thread/WARN] [minecraft/MinecraftServer]: Can't keep up! Did the system time change, or is the server overloaded?
I have been playing this pack for a while with a buddy of mine. I host the server on my PC and join it myself. It hasn't been an issue at all until now since my PC is a beast and my connection also has enough upstream to not be an issue.
My PC has the following specs:
Intel Core i7-8700K @ 4.3Ghz 32gb (4x8gb) 2600mhz RAM Samsung 970 Evo NVMe SSD (System disk and running MC server - client run from secondary SSD)
My server start script:
java -Xmx10G -Dfml.queryResult=confirm -jar forge-1.12.2-22.214.171.12468-universal.jar nogui pause
The warning/can't keep up message happens more and more often and tonight it was worse than any time before. I hosted the server from my PC as normal and connected to it from work and my buddy connected like normal. It was unplayable.
Does anyone know what to do to fix this?
EDIT: Also it's v3.50 - updated the server a few days ago from 3.42 with no problems.
