1.14 Vanilla Server Lag / World generation problem.

Hello,

I want to inform you that with Vanilla Minecraft 1.14 servers have a problem with generation. All servers of Vanilla Minecraft 1.14 have 20000+ms This problem is not with my machines. I tried with 4 other machines and the problem is global with 1.14. I asked other hosting companies and they have the same problem with Vanilla Minecraft 1.14 servers

  • On other versions like Vanilla Minecraft 1.13.X there is no such this problem.

Console errors:
-------
[Server] Server thread/WARN Can't keep up! Is the server overloaded? Running 19877ms or 397 ticks behind
[Server] Server thread/WARN Can't keep up! Is the server overloaded? Running 16605ms or 332 ticks behind

I am also seeing this problem on a vanilla Minecraft server. We were playing on a new world created on 1.14.3. Played successfully for many hours over the last 2 days. Just today we went to a village that was being raided. The server crashed with the error attached (crash-2019-07-01). Now every time I try to go back into the server, it crashes within a minute. Nothing was changed on the server.
