Worlds crash on "saving world" when running a LAN server

I have continued to experience this issue on 1.21.11 but I took a while as I wasn’t able to reproduce it for a while to gather information the computer acting as the server crashed while seeing “saving world“ and resulted in a “Minecraft ran out of memory“ - “this may be caused by a bug in the code…“ error the other two computers just lagged a bunch then got timed out of the world

The crash did not occur on the first occurrence of “saving world“ but I don’t know of any other factors involving the crash
I attached the log I believe is the one relating to the bug

Thank you!

Environment

The server was a custom computer running Windows 10 with 16Gb of Ram
Both clients were Dell laptops running Debian 12/13
performed on 1.21.11 vanilla

Hi!
Thank you for your report! 

Could you please provide more details or/and media files. As we have no repro of this issue. 

  • Are you using any data packs? If so, could you provide a complete list of them?

  • Does this issue still occur on a new LAN server without any data packs?

  • Did the issue happen only once, or does it occur consistently?
