![Proxmox 系统每日崩溃](https://linux22.com/image/152739/Proxmox%20%E7%B3%BB%E7%BB%9F%E6%AF%8F%E6%97%A5%E5%B4%A9%E6%BA%83.png)
我一直在凌晨系统崩溃。 00:00 至 08:00 之间。
查看日志,看起来每个核心都慢得像爬行一样,最终崩溃,直到整个系统冻结。从第一次错误到系统崩溃大约需要 25 分钟。这些错误让我想到内存问题,但我不确定这是否只是因为其他一些故障。
该系统是 Super Micro X9DRW-IF,配备双 E5-2630 V2 和 16X 8GB DDR3
操作系统是 Proxmox 最新
核心:
Linux pve1 4.15.18-10-pve #1 SMP PVE 4.15.18-32 (Sat, 19 Jan 2019)
PERF 中断开始花费越来越长的时间,并且内存错误开始发生。在系统冻结之前的 20 分钟到 1 小时内,大约会出现 20 个此类错误。据我了解,PERF 只是 CPU 节流。它会限制到尽可能低的速度,此时系统会缓慢爬行。

此时我只想了解实际发生的情况。
答案1
我的主机托管主机拉出了服务器并重新安装了所有 DIMM。
这种情况已经 3 天没有发生了。看起来,由于缺乏可靠的连接,连接速度变慢,越来越多的数据被损坏,直到系统在尝试跳过坏地址时崩溃。连接松动也可能导致内存电压下降,从而导致波动。电压保持在范围内,但随着这种情况的发生,电压会变得不稳定。
