Server crashes every day

Hi, my server crashes almost every day, I can't find the reason for the crashes, because everything is fine on the second server with the same plugins.

There is one plugin that I find suspect

This plugin is called Rust:IO Clans by the author playrust.io / dcode

Rust:IO can cause all kinds of problems, you are better off without it IMHO
