NUC with Centos 7 crashing: Microcode SW Error Detected
I am trying to figure out why the WiFi on my Intel NUC with CentOS 7 continues to die. As info, I have 5 node Hadoop cluster and they are all configured the same (as far as I can tell), however, the other machines which are on WiFi do not crash. I don't know what is wrong with this particular machine.
Here is the error from /var/log/messages. It is the same message that I see regularly as I've been watching this problem for days.

Where should I start trying to debug? I can edit the original post with updates.
Here are some things which I think might be helpful:

I am trying to figure out why the WiFi on my Intel NUC with CentOS 7 continues to die. As info, I have 5 node Hadoop cluster and they are all configured the same (as far as I can tell), however, the other machines which are on WiFi do not crash. I don't know what is wrong with this particular machine.
Here is the error from /var/log/messages. It is the same message that I see regularly as I've been watching this problem for days.

I am trying to figure out why the WiFi on my Intel NUC with CentOS 7 continues to die. As info, I have 5 node Hadoop cluster and they are all configured the same (as far as I can tell), however, the other machines which are on WiFi do not crash. I don't know what is wrong with this particular machine.
Here is the error from /var/log/messages. It is the same message that I see regularly as I've been watching this problem for days.

Where should I start trying to debug? I can edit the original post with updates.
Here are some things which I think might be helpful:

I am trying to figure out why the WiFi on my Intel NUC with CentOS 7 continues to die. As info, I have 5 node Hadoop cluster and they are all configured the same (as far as I can tell), however, the other machines which are on WiFi do not crash. I don't know what is wrong with this particular machine.
Here is the error from /var/log/messages. It is the same message that I see regularly as I've been watching this problem for days.

It seems the wifi drivers cannot manage the wifi hardware in your NUCs.
Several linux distros can be tried live without installing. I think NUCs have Intel wifi, which should work with built-in linux drivers, but they must be new enough.
I have a NUC with Intel 6th generation hardware. I have noticed that older versions of operating systems cannot manage the wifi hardware, but newer versions manage it without any tweaks, 'out of the box'.
- Edit 1: I tested with live systems: Ubuntu 18.04.1 LTS can manage both the wired and wireless hardware of my NUC6i3SYH. Debian 9, Stretch, can manage the wired network automatically. I failed with the wifi, but other people might fix it (I don't know if there is a driver problem or if I cannot manage the user interface for wifi in Debian.)
- Edit 2: I downloaded
CentOS-7-x86_64-LiveGNOME-1810.isoran it live and it can manage both the wired and wireless hardware of my NUC6i3SYH. It was started as easily as with Ubuntu 18.04.1 LTS. But I have not tested the stability during a long time.
Edit 3: You should consider that the hardware might be damaged (for example failing when getting hot). But if it works well with another operating system, you can conclude that the hardware is good.
When was your NUC hardware developed, and when was the CentOS 7 software developed?
Centos 7 has an old kernel series, 3.10; the kernel version in the live system '1810' is
3.10.0-957.el7.x86_64 #1 SMP. Ubuntu 18.04.1 live has kernel version 4.15.0-29 and an up to date installed system has 4.15.0-43.- Please try with another operating system with a newer linux kernel with newer hardware drivers.

It seems the wifi drivers cannot manage the wifi hardware in your NUCs.
Several linux distros can be tried live without installing. I think NUCs have Intel wifi, which should work with built-in linux drivers, but they must be new enough.
