[MC-130040] Server crashes instantly after connecting

I have no idea what I did wrong. I went exploring to find a mesa biome to get some red sand.

And now my server contantly crashes until I teleported myself to the spawn using the server console in the small time window I have.

I hope the crash report helps!

This is the server watchdog

Description: Watching Server

which kicks in because the server runs out of memory:

Memory: 1370375216 bytes (1306 MB) / 1970274304 bytes (1879 MB) up to 1970274304 bytes (1879 MB)
	JVM Flags: 2 total; -Xmx2048M -Xms2048M

Maybe this is a similiar issue like MC-129492.

Assign more RAM and report if the issue is persising.
