Server power on but unreachable

NethServer Version: Final 7.3
Module: System
Hi everyone,
In one day it has happened two times.
I find the server turned on but not reachable by web or console.
I have to restart and everything resumes normally, I think of a HW problem.
Is there a log I can consult to find the problem?
Thank you

For potential hardware failure, first place to look is /var/log/dmesg and after that /var/log/messages

Hi,
I didn’t find /var/log/dmesg bat in /var/log/messages l found this values:

I found also /var/log/dmsg.
How do l read this log, what i havo to look for?

Hi…
It happened again, I had to force the server restart manually.
Nobody knows how to help me?
Thank you

When it happens do you still have physical access to a working console?

You should look for hardware errors.

Basic problem with logfiles and hardware errors: Maybe logging is already dead.
Did you look in your BIOS? Maybe you find something there…

If the system is frozen, maybe there’s an error message on your server screen…

No. i must restart phisicaly…

In server screen nobody. I look for in BIOS.

in the message log, I see that before the reboot, the server goes to query ip 192.168.122.255 which is the sub net of the virtual machine’s default network adapter.
On Saturday, I disable the virtual network adapter and still and the problem has not yet reappeared.
there may be a relationship?

I suspect of the kernel and Intel i915 graphics.

If it still works I think it’s a problem with the virtual network driver. Can you tell us something about the configuration please.

since I disable the “default” network adapter in virtual machines, it has not happened anymore.

My configuration:

Can you post a few lines before to a few lines after the message. I try to find out what is happening here.

The pictures you posted are very small, I can’t read anything. But what I get is that you install a virtual mashine at nethserver. So it shouldn’t be a driver problem.

Look for here…
