observer core报错

OceanBase 技术问题
#1

【 使用环境 】测试环境
【 OB or 其他组件 】4.3.1
【 使用版本 】
【问题描述】observer产生core文件，这个如何操作将observer正常运行，看日志是内存不够用？
【复现路径】正常部署后导入一批数据，不确定具体操作啦，时间有点久
【附件及日志】core文件：

#3

麻烦发下操作系统具体版本以及core时的observer.log

出现core可能触发了bug，可以升级到4.3.3版本

#4

环境已经不存在了，大概率是一个zone下的observer都被kill掉了很长时间，后来又手动启动了下，那么这个时候zone内的数据还会同步么？还是说需要从集群中删除这个zone然后再做扩容操作

#5

手动启动后会自动同步，只是这个情况全量数据都需要从其它副本拉取

#6

可以再确定下是4.3.1版本吗？环境不在了是吧
进入安装目录bin下
/home/admin/oceanbase/bin

执行
./observer -V

#7

observer (OceanBase_CE 4.3.1.0)
