我们刚刚收到一台全新的双CPU服务器，在启动后不久发生内核崩溃，甚至在操作系统设置空闲时发生。 我能够安装操作系统，并启用mcelog来尝试和了解发生了什么，虽然我不知道如何使输出。 在线阅读让我觉得这可能是其中一个套接字（1）上有缺陷的DIMM，但我跑了几遍memtest，发现没有错误。 有没有可能这是一个软件问题呢？ 我已经尝试了2个操作系统，两者都发生了相同的事情，尽pipe在Debian / Proxmox中发生的事情比CentOS更常见。
服务器规格：
双Intel 8核Xeon E5-2620v4
2个DIMM 32GB DDR4 2400MHz RECC DDR4
MB SuperMicro X10DRL-i
这不是CPU散热问题，因为在memtest或操作系统安装过程中，这些温度从未超过35ºC。 在CPU崩溃之前，我也能够在CPU上运行一些短裤基准，而且临时工也没问题。
我怎么知道这里发生了什么？ 我可以访问服务器几分钟才发生，我已经下载了vmcore转储，但我不知道如何处理它。
这是引导后50秒，然后坠毁mce日志：
