Hello,

I am having some issues with my server, It happened to me a while ago with another build that I had but this time is really haven't done what I did to the last one.

The problem is that my server keeps disconnecting from the network and I notice that the blinking HDD light on my case goes out, when i try to access my server it keeps disconnecting. I usually have to restart the server but I don't know why. It usually happens late at night when I go to sleep or sometimes after just an hour of booting back up. I know that is is bad to restart the server from time to time like that but I have no way of accessing the server.

One thing that I noticed is that when I restart the machine i check for updates and there is a new update. I update it and it last for a few days until I have to restart and then install new updates.

I am not sure what it could be, I check syslogs and I do see serval things that pop up on the last minutes of the connection


Such as:
"entered blocking state"
"kernel: RIP: 0010:lock_page_memcg+0x23/0xa0"
"kernel: RIP: 0033:0x7f9226d95699"

I just don't know how to deal with it.


Any suggestions or ideas would be greatly appreciated.

please post the complete trace and a few lines around it - then we might have a better idea where the issue is
(please post as text inside code tags)
 
Here are the logs that I keep getting, Not sure where it starts. I kept seeing kernel issues so i think it starts from there

Hmm - looks unfamiliar ...

* do you have containers (pct/lxc) running on that machine - if yes - do you have any non-default configs enabled for those containers?
* do you have made any modifications to the configuration - compared to a plain PVE system?

else:
* the BIOS is from 2018 - I'd recommend to upgrade it - since these things can be caused by an outdated BIOS (+new kernel)
* last but not least - I'd suggest to run a memtest for an extended period - maybe it's a broken memory stick

I hope this helps!
