It ran out of memory as the last line says.
Maybe you have too many mods, machines or other things that put a heavy load on the server.
Yes i saw that too, clear lag is optimized to limit entities spawn, it also kills entities who are alive more than 100 seconds. i also limited global chunks to 1200 and the world is on optimize mode, so unused chunks get destroyed. i recently destroyed all unused chunks with a program. I don't have any mods, i have 17 plugins. i analyzed RAM usage during playthrough, it keeps going up and down from 400 to 1400 with 5 players online. what i don't understand is that, a month ago i had like from 7 to 12 players online, all the day, and the server could keep up. i don't know why, it started to crash 2 weeks ago, and now every 2 hours it crashes.
