这个问题竟然还能重现，第一次我提交问题的时候是ubuntu，想着可能是操作系统不兼容的问题，后来这次我换到centos7.9，还是一样的问题。

我的OCP、OBServer是分别装的，用的是16C32G的两台虚机分别承担，OCP是用obd进行直接安装，没什么问题，然后OBServer是利用OCP的agant去安装的，每次都能看到这个问题。

万分感谢

是因为CPU不支持avx指令集，如果是虚拟机 并且cpu硬件支持 可以增加一下

最新版本要cpu支持avx指令集了，要么开启要么降版本。4.2.2.1

#10

too many arguments Illegal instruction (core dumped),得看具体的dump文件内容

#11

自己使用的是proxmox创建的vm，首先需要检查宿主机是否支持avx。
使用如下命令检查：

grep -o 'avx[^ ]*' /proc/cpuinfo

如果支持avx。
将proxmox的vm中cpu类型改成“host”

重启虚机，问题得以解决。

谢谢大家的帮助
