im running a daily minecraft server and its running absolut fine. 

it has crashed for the second now and im confused of what is causing this crash. it is timing players out and it shuts down itself.

i have allocated 16gb of ram and there is normally 12 players on(not a big server)

my cpu is i5 6600k.

when im running minecraft on the same computer it doesnt peek to 100 prosent. it stays at 20 prosent all the time.
