Hello there in my 1st post, recently I switched to MC 1.13.2 and I have a VPS (1vCore CPU, 1GB RAM, 20GB SSD) until then I was on 1.12.2 and it was working well. But now the hole process freezes frequently and today it causes to stop completly and it restarted in background which forces me to kill server's process in "htop" because it took entire CPU activity. I have enabled something in "update" folder I have no idea what that is for because it is not even working.
Server crash log:
