集群铲掉使用obd demo部署或者obd web白屏化部署试试。

obd web白屏化部署，一样出现同样的问题，部署成功，部署后一阵是正常的，后面就出现停用了

observer日志发一份完整的看看，~/oceanbase/log/

log.zip (35.9 MB)

防火墙关闭了么

sudo ufw status
Status: inactive
关了的，要是有开，我也不能在本地连接到内网服务器的部署的oceanbase了，就是不知道为啥过段时间他会自动停用，是配置问题？我使用的是最小安装模式

看下这个呢
sudo ethtool ens18
cat /sys/class/net/ens18/speed

看一下楼上镜水老师的回复，获取一下
sudo ethtool ens18
cat /sys/class/net/ens18/speed

麻烦用obdiag诊断工具收集一些信息看看。obd部署的话会自带obdiag工具：
obd obdiag gather scene run --scene=observer.cluster_down

obd obdiag gather scene run myoceanbase --scene=observer.cluster_down 导出了空的文件夹

obdiag 版本较低吧 可以先升级一下最新版的

单节点 6G内存不稳定的话，推荐配置是什么

6G是最小规格配置 不适合应用生产环境
推荐可参考该文档https://www.oceanbase.com/docs/community-observer-cn-10000000001879714

这个oceanbase-all-in-one-4.3.4_20241108.el7.x86_64社区版就没有能稳定运行的吗，要不然就卡在 Initialize oceanbase-ce 重试几次就行，要不然就运行一段时间 oceanbase自己挂掉，配置都按文章可选设置了，还试了好几个服务器，都一样，还找不出问题，试过docker部署和 使用 systemd 部署 OceanBase 数据库都不行，搞不明白，是系统问题还是什么问题

找不出原因，可能是触发了什么被系统干掉了，已换4.2.5长期支持版，支持utf8mb4_unicode_ci，稳定运行一天了，没有OLAP的场景就不推荐最新版
