Stability issues with LXC containers running

[DzAirmaX]

Hi team,

First, thanks for your work. Proxmox looks like a robust project.

I am encoutering some stability issue with my server: I thought first it was link to my Hardware (like a bad HDD or a faulty power supply).

But all of the tests came back good (Memtest OK, SMART OK, stress test by recompiling kernel OK). What I noticed is that the host will be rock solid only if no LXC are launched ...

After launching lxc containers, after approximately 2 days, the system hangs. No log are available, I did install Kerndump and mcelog but impossible to get information on the reason why it's crashing. The screen is frozen on the login and the host is unreachable.

I can provide more details if you need those, please help I am getting out of ideas ...

A few questions:

• How many containers are you launching?
  
• Are they resource intensive? i.e. eating up memory/CPU
• Is it a clustered setup?
• Free version or supported version?
• Is this a fresh install?
• Have you tried running VMs as opposed to CTs?

Please provide hardware specs and container configuration values (screenshots with any IP or other identifiable info blurred out would help).

Ok, I finally found the solution!

The problem was linked to the CPU bios settings: CPU C-State were a really bad idea... Now everything is stable!

PS: I deleted my previous posts for clarity
