用 podantiaffnity 试试

@blackeeper 试了这个倒是没事儿
@mdeche101644 没有产生，只有内核崩了才有我记得

@msg7086 #17 oracle 的，看上去可能稳定一些，我调研一下

@ruidoBlanco #19 已经是 1160 了，是红帽 7 的最新的内核了，再升就得用 elrepo 或者楼上说的 uek 内核了，领导估计不大支持升级

hang 住时候的内核日志截取了部分

@ruidoBlanco 一会就补上老哥
@lrvy 一言难尽，反正就是能用红帽的包，但是人家不管我们出的问题

@Hormazed #8 生产系统不是非常敢用 elrepo 提供的内核，尽管我也想用新的
@Hormazed #9 我们的内核版本已经比这个新了，是 1160
@JackSlowFcck #11 周期太长了，机器托管到别的机房了，现在有的业务是单点，只能先再用上了
@Kumo31 #10 大概率我们要 3.10 一直用上去了，我们还有信创的机器是 4.19 的内核，也反馈过 bug ，厂商也没管

@hefish #5 只是怀疑，因为 reboot 了就好了
@liuchao719 #6 没人敢用新系统，没人背得起锅，大家都用老的

@iyiluo #1 当时看带外硬盘信息是正常的，而且 reboot 后恢复了，运行 1 天了也正常了
@barrysj #2 有，从监控数据看到当时有一块盘的 I/O 掉下去了，突然没有读/写了，进程也都 hung 了，iowait 当时没有
硬盘是 3 块 SAS 的 SSD 组的 RAID
