PLEASE READ BEFORE YOU MARK THIS AS RESOLVED AND DUPLICATE!!!!

Yes, I have created this issue before ([MC-210978|) and [mod] violine1101 answered with the following links:

1. MC-124672 

This solved the ambiguity "problem".

2. MC-124672

This was meant to explain the problem with the stuck spawn area, but it was not the case, so I answered with this:

Thank you for answering so fast.

To my understanding the warnings are not a issue.

 __ 

But for the part where the spawn area doesn't load, please take into consideration 

 __ 

first, that my PC is powerful enough (gtx1070 and i7 6th generation) and it has enough RAM (16) to run the server and

second, that the "Preparing spawn area" screen doesn't log the same progress information multiple times as in the linked issue.

It only happens 4 times before the server eventually "starts". So it doesn't happen as often as in the issue you linked.

I did not get an answer to this.

Original issue ([MC-210978|) :

-------------------------------------------------------------------------------------------------------

Hello everyone,

I have the following issue:

I made this server with my computer to play only with a friend. Today we couldn't connect to the server.

I launched it as usual with a run.bat because I allocated 3 GB of RAM to it:

C:\Users\myname\Desktop\server_folder_name>java -Xmx3072M -Xms3072M -jar server.jar nogui

The 2 obvious problems I see are the warnings at the beginning and the spawn area not loading.

Do you know how I can solve this? Is it maybe a known issue? 

Thank you everyone in advance!

A little UPDATE to this issue*
