I run the server on an 64bit Ubuntu 16.04 with 64bit java Plugins list http://prntscr.com/ez6l8p
From the CPU model name, I assume you're running this on a VPS? If so, how much RAM does the VPS have? What's happening here is that the VPS is running out of RAM and Java is crashing.
Some hosts do the ram sharing thing, where if you dont use ram others get it. Maybe you have short spikes that need ram but your host not fast enough to give it?
Try allocating 5GB. If it's still crashing, then it's likely your host is overselling to the point where there simply isn't enough RAM available on the machine.
You should just keep it on half of your max memory, leaving enough space for background services like sshd (OpenSSH) and the network thing (I did ubuntu stuff a few months ago so I forgot its name)
Also you may want to change your garbage collector. (For java 1.9 < the default one is a bad GC mostly suited for client apps with < 256mb memoty usage) (And most likely GC is your problem, from the log you can see that it tries to initialize memory, but can't allocate single big chunk of it)
Wow, thank all of you for the impressive feedback. Do people recommend me to buy an dedicated instead? If yes which one? I got it working with changing it back to the default garbage collector. But I kinda need a new one, don't I? My VPS got this. OpenStack KVM 2 vCores 2.4 GHz 8 GB RAM 40 GB SSD Local RAID 10 It is from OVH.
It's nothing to do with his choice of garbage collector. jvm_args: -Xms7024M -Xmx7024M You are trying to start your server with 7gb of ram, but your server does not have 7gb of ram free. In general -Xms is redundant anyway.
Okay so I'm fine with the standard one? Like, I tested so many Garbage Collectors, and everyone makes it worse, lol. So the server is the problem. But 6 GB ram is fine right now, I am just setting the server up atm. But I got contact with a rather big Youtuber, so the server has to handle 80+ players. What specs would the optimal?
