Can't figure out why server keeps crashing on its own

[Professional Derp]

Hello,

 

I am running a forge server on a Google VM which has 7.5 GB of RAM. I am running the server with 6GB. For the past few days I have been able to play perfectly well. At some point when I was on the server the server closed on its own and when I restarted it the whatever I did on the world was not saving and I started at the moment right before the initial crash. Even the server backup (AromaBackup) failed. So I figured it was due to my internet connection and logged off and left the server on its own. A couple of hours later the server was offline again. So I started the server again and this time never logged on. Same result. I tried looking through the logs but did not understand anything. Here is the latest.log: https://pastebin.com/QsrT12Je. Please help.
