Linux上的Minecraft服务器运行不到一小时就崩溃

1.18.2私服，没有装任何服务器插件和模组，使用的server.jar是官方的。只有两个人游玩

服务器崩溃没有任何条件和征兆，甚至没有崩溃报告
无论是否有人在线都有可能崩

尝试过重装java，但是没有用
是内存堆积过多导致的吗？（对java和linux都不太了解

内存分配：6g
java版本：java18 （jdk

报错：

服务器配置：

平台 ：Amazon Linux （好像是CentOS来着？）
vCPU数量：2
性能应该还可以，起码能支持两个人正常游玩

崩溃表现：

经常玩着玩着就掉线了（三十分钟到一个半小时不等）
朋友还问我为什么关服之前不通知一声（
从minecraft客户端看就跟服务器正常关闭了一样
