我的服务器老是莫名奇妙的崩溃，我不知道是什么原因，各位大佬可以帮忙看一下吗

我是1.12.2版本的海绵端

server.properties 中设置 max-tick-time 项为 -1

建议换一块主频高一点的 cpu

第一个报错是NPE
onEndTickMapOptimization

第二个是单个tick跑了80s 被强制关服了

两次情况不一样
当时服务器有什么事情发生么
比如玩家在做什么？

有人说在暮色跑图 有人说在做巫术的成就 还没找出来比较明确导致崩服的原因
我再观察一段时间吧 谢谢大佬们

好嘞 感谢大佬！

5.10的崩溃
代码似乎的确是卡在成就相关的方法上面了
