问题

我的机器很奇怪...计算机的CPU负载过大(在8核机器上大于4),但是没有一个进程占用大量CPU ,尽管机器的8核正在经历高负载( htop显示它们都在30-70%的之间振荡)。

主板:Asus Z10PE-D8WS CPU:Intel(R)Xeon(R)CPU E5-1620 v3 @ 3.50 GHz RAM:2个Kingston 16Go PC4-2133 CL15-ECC寄存(KVR21R15D4/16)硬盘:2x 2 Raid0 ATA ST2000DM001-1ER1

内核日志中的奇怪的行:

答案1

看起来你有一个坏内存模块,机器不停地暂停,等待硬件自己纠正这个错误,你需要尝试删除或替换第一个CPU,第二个通道和第一个插槽的内存,

希望有帮助。
