同仁们给点建议

现在服务器的硬件质量比以前差多了。
我单位上个月新加的硬盘，这个月坏了两块，幸好有冗余。

让IDC机房的运维把内存条更换后没有报错信息了。

才装一周的数据库服务器，装的第二天就查看了好像也有这个问题，只是当时很很忙没有仔细分析，今天运行dmesg命令发现有错误，所以在坛子里来发个帖子问问，我让机房的检查一下内存的情况

The error message basically means that the memory you install is faulty. The system has found that the memory was corrupt and the ECC was able to correct the single bit error and alerted the OS to the fact that the memory is unhappy.

The DRAM in question is the DRAM in Bank 6 (most probably dual channel memory) so look at that location for the faulty ram.


1. 是否最近动过 内存 ？　增加过内存类的硬件？

2. 建议SA 和 HW vendor 检查 DRAM设备
