Hello, I have a problem. My PVE is crashing randomly, at the moment everything is working, and at any moment without even touching it, this error message appears on the display and nothing else works (GUI, SHELL...), the VM/CT freezes, I have to force the server to shut down with the button.

Virtual Environment 8.2.6
Linux pve 6.8.12-2-pve #1 SMP PREEMPT_DYNAMIC PMX 6.8.12-2 (2024-09-05T10:03Z) x86_64

Absolutamente o mesmo comportamento aqui. Estou investigando isso há uma semana e, por enquanto, decidi fixar 6.5.13-6-pve.

Hey my friend, thank you very much for the topic, I went back to just 1 version 6.8.12-1-pve, I'll check the behavior, and if it's still bad, I'll go back to more versions.

thank you very much!

sorry my english for google translate :p

it also crashed on 6.5 for me. I contacted the support of my server provider and asked for a BIOS update. Until now it is working. Before, I could trigger the error with my wireguard in a lxc container. As in the thread I have referenced the BIOS update really seems to help.

Hello my friends, yesterday (09/24) I made some changes to proxmox that seem to have solved the problem so far.

1. I turned off a crontab that I used to read the temperature sensors.

1727270218189.png

2. I removed some VMs (ubuntu desktop and kali shell) both as host CPU

1727270248874.png

3. I activated VLAN aware on the LAN, this was causing some errors in the system log:
..entered blocking state
..entered forwarding state
..Link is down

1727270142502.png

I believe this could be a compatibility issue with VM/CT, if possible, turn off some, or if you are using host, switch to virtual CPU, it is just a suggestion.

Well, these were the changes I made, I have been 12 hours without crashing (I was not online for 4 to 5 hours), it seems to be solved, I will report back within the next few hours.

We are trying..
 
Thank you for reporting back. Indeed I had the same messages in the journal regarding the network interfaces.
And i can confirm making the bridges VLAN aware made these messages vanish. did not have any effect.
I am not sure regarding the cronjob you talked about, since it seems useful to me... - lets see if the vlan setting fixed it already.

I have replied to this post about this with some image and how this error can be reproduced.

Hi, I saw that you still have a problem, I'm working hard on this to find the reason for the problem. Yesterday I turned my crontab back on and less than 10 minutes later the problem started again.
So I went to see if there was anything related to the lm-sensors package I was using, and I found this.
https://community.frame.work/t/resp...ror-causes-missing-sensors-on-linux-6-7/47767

Now I turned off the crontab and my PVE is back to normal, I now have 12 hours of Uptime again.

This could be one of the problems, but it could be just this one.

Check if you have this package (lm-sensors) installed, if so, remove it.

apt remove lm-sensors

I don't have any crontab, and I can reproduce this error by just clicking 'Refresh' (pve web). ^^

I have even stopped the crontab completely, and it still happens.

Me neither. Does your system completely crash? After a bios update my system is running for 3 days without totally freezing. However, I still have random segmentation faults with pvestatd.
A simple
Code: 
service restart pvestatd
makes the webinterface available again.

when I play with pve web manager... there is the problem, if I don't touch anything, everything works fine... but the error is still there.

and crashes can occur at any time

if you see the images in the other post, you can see that sometimes it crashes completely, and sometimes it's just the error but the kernel still works.

I understand that, but do you get CPU softlocks/hardlocks so you have to restart the machine, or is it sufficient to restart the service.

Not always, but in most cases I have to manually restart the entire server.

- At this point I am going to reinstall proxmox on the same hardware, different disks and without upgrading anything from proxmox to see what happens.

I have had the server active for more than 7 months and nothing has happened, that it is happening now seems very strange to me.
