请问各位有遇到过 gnome 会导致系统崩溃的问题嘛？

请问各位有遇到过 gnome 会导致系统崩溃的问题嘛？

之前这台 oracle 是其他开发部署的，然后没交接就到我这里了。
系统是 centos7，装的 gnome 。
前阵子频发故障，查了一下 IPMI 发现是硬件的问题于是找厂家换了硬件。
可这个星期回来发现星期五晚上又挂了，直接死机和之前状态差不多，尝试热重启后发现。 只要进 oracle 账户里启动 dbstart 系统就开始走 crash 流程，保存 dump 文件然后重启。

查看了 log 文件发现只有 desktop，gnome 的相关的大量错误日志，dump 文件就没看，也不会看。
索性就想直接把 gnome 卸载试试，结果每次运行 yum remove 都会崩溃重启。
换了个思路，启动时默认启动 console，成功卸载，进入 oracle 账户也正常启动，到现在已经 2 个小时了暂时没出现之前的故障。

以为看不懂 dump 文件所以究其原因也没办法细察，索性就来问问 V2 的各位大佬，GNOME 会导致系统崩溃嘛？本身是内网专网环境，一直用也没更新，怎么好好的就爆炸了呢？？

    crash 有一个 dmesg，有基本的 panic 日志，可以先看一眼，不一定是 gnome 的问题。

    说实话看起来还是硬件错误，不如继续找浪潮看看？

    @barathrum #3 已经让浪潮的人在路上了，感觉 CPU 也不利索，这次让他们把 CPU 都换了看看吧
