Attached is a debug report and a new crash report as the server crashed right after I made the debug report
I also have the same problems and I can even show it using an image as I host both 1.12.2 servers and one 1.14.4 server, and if you look at the image that I have attached, it is the upper one being the 1.14.4 server with 1 player on, and the lower one a 1.12.2 server with 1 player on.
I have chosen to strip all other things as they are not necessary to illustrate it.
I'am sending the debug report in the next message, so only the Users can see it.
The server have:
2x Intel Xeon E5603
Minecraft Server have 8 GB RAM
The operating system is Windows Server 2016 64bit
Java Version: 1.8.0_201 64bit
Sometimes the Minecraft server with 1.14.4 stops itself and reports that it is doing so because it is running too many ticks behind.
I get this message right after I restart the server, even if no players are joined.
[16:31:37] [Server thread/WARN]: Can't keep up! Is the server overloaded? Running 2364ms or 47 ticks behind
The water problem are the same in survival, in all world's
Also affects Java version 1.14.4
It's the same problem as Rob Edgler's comment about Win 10 Bedrock version 1.12.1
