Proxmox Node crashes randomly

[r0g]

Hi,

in the last two months my server has been crashed randomly. However, I have not been able to determine the cause by reading the log files. Can anyone have a look at these logfiles and help me?

I've already contacted my hoster and he did a complete hardware test that took about 13 hours, but they didn't find anything.

Can you post your syslog between the time the server crashes?

Yes. See attached file. Server crashed at 12:31 and at 12:50 i rebooted the system manually.

For me it looks like the server restarted normally at 12:31, doesn't it? But unfortunately I have no idea why... Any ideas?

Strange... didn't see anything helping on the fast. Server up do date? Maybe an bad hardwareissue. Was something changed on the server?

Some days ago i created a new VM and restarted the node after 48 Days uptime and now - 1 week later - the node crashed...

My Version:

Kernel Version
Linux 4.4.83-1-pve #1 SMP PVE 4.4.83-96 (Tue, 19 Sep 2017 10:30:12 +0200)

PVE Manager Version
pve-manager/4.4-18/ef2610e8

Do you think replacing the whole hardware except HDDs will help?

This is really hard to say... What HW do you have? CPU/MEM/HDD/SSD/RAID
What does

pveperf /your/storagepath/

say?

Ok. Your hardware looks fine. So it looks for me an selbbuild server, so no support. What can you do? You can do an Firmware/BIOS/Controller... update do the latest version of it, reset the BIOS to defaults, and reconfigure it new with your settings. Deactivate alle powersaveoptions in the bios.

Later an Update to 5.1. But it looks for me an HW-Problem...and/or... we will see.

In fact, the BIOS version is very outdated. I will ask my hoster to update the BIOS version and then continue to monitor the stability. Thank you very much!
