Environment:

We run this server on windows 10.
Home hosted.
Ethernet connection to modem/port-forwarded through modem.
Leaving our player alone will make the disconnection take longer to happen.
No error messages in the console.
Updated java.
I have restarted our modem and router.(even though we go straight through the modem.)
Our modem is a modem/wifi combo with the wifi disabled.
The server PC is accessed by teamviewer and has nothing but server info on it.
I connect to the server using a ethernet cable into the same modem and still get disconnected.

Run.bat file:
ECHO OFF
:start
java -Xms512M -Xmx4096M -jar spigot.jar -o true
goto start 
PAUSE

(we usually don't have the -Xms512M in but tried it to see if it fixed our problem.)

(We have other plugins but had them removed to stop errors and keep them away while working on more important plugins. They don't have an effect on the disconnecting problem at all as far as I know.)

I took out some text from the log because I went over the max length. Nothing important.
Example of things I removed from log.

 Description   

I have been using spigot for a while and had no problems running a server. Recently after updating to 1.11.2 my server would disconnect players. It would run fine then suddenly all the players would start lagging and no commands would work and within 15 seconds everyone would disconnect with this message.
(Player lost connection. internal exception java.io.ioexception an existing connection was forcibly closed by the remote host)
As soon as they disconnected they could reconnect with no problems. Also if a player would start lagging they could quit the server and re-log and this would skip the whole error message and disconnecting. Sometimes it takes 10 minutes to do this after joining and sometimes it does it every minute. We fixed this by changing the run.bat file to use a max limit of 8GB instead of 12GB. Or from leaving the server running for a long time. I'm not sure what fixed it because most of the players were all busy during this time and didn't play on the server at all. Since fixing it we have had no problems with random disconnecting. Now after updating to 1.12 or 1.12.1 (both have these problems) this problem came back up and won't go away no matter what we try. Sometimes all players will disconnect but 1 but other times all players disconnect. We have had just a few players on because of this problem and from working out bugs and this disconnecting still happens with just 2 of us.

What do you think it is coming from?

Existing connection forcibly closed by remote host is not a spigot issue
