[MC-134515] 1.13 Server Can't keep up!

Plain vanilla server started

Immediately started getting WARN Can't keep up! Is the server overloaded? Running 2042ms or 40 ticks behind

Used to host a 1.12.2 server on same hardware with no issues.

ALSO - same issue on a Dell Poweredge R720 rackmount server. Dual Xeon processors with 64gb RAM

Anyone have any ideas?

Is this a new 1.13 world or a 1.12 world?
If the latter, did you optimize the world?
What's the server startup script?

brand new 1.13 world created with all default settings

Not optimized, fresh server.jar from Mojang

No startup script, just double clicked the .jar file. text copied from server gui.

These issues happens most when exploring new parts of the map.

I usually fix that error by maximizing my allocation for my launcher to 4 GB.

-Xmx4G -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalMode -XX:-UseAdaptiveSizePolicy -Xmn128M

java -jar minecraft_server.jar nogui

Using the version without an extra GUI may also help improve performance, thought I'm not sure if this is the cause of the problem you are experiencing.

@unknown, @unknown, without adding any -Xmx argument you get only 256 MB of heap, which is not enough to run a server.
