服务器每天都要蹦一次，原因不明，观看后台日志是以下：

[17:56:36] [Server Watchdog/FATAL]: A single server tick took 60.29 seconds (should be max 0.05)
[17:56:36] [Server Watchdog/FATAL]: Considering it to be crashed, server will forcibly shutdown.

经过我初步分析是TPS过低导致的，那么是什么原因导致TPS过低呢，没找到原因！！！我也是一脸蒙蔽，求大佬帮我解决了这个问题，感激不尽。。。

嗯
像这种混合模式群组服务器
一般处理器不好或者内存分配的不够多
都会拉低TPS的
推荐安装下优化插件
一般大型服务器不装优化的话TPS会拉低

我看也像是优化、内存分配不好导致的，导致TPS太低，导致崩溃，可以进行全方位的群组优化分配，定能解决。
谢谢你的回答，不过有一个服不能装插件，只能人工手动来进行优化分配内存。

这个服不能装插件，能否修改核心等配置进行优化呢

核心建议你不要修改
以免无法开服
服务器的配置文件里可以修改最大视距
视距调小了区块加载就少
也就更流畅
有些服务端是可以进行优化的
你也可以搜下该服务端的优化教程

好的，正在看，看看这两天这个问题解决了没，如果解决了给你最佳。感谢你的热心回答
