Proxmox 4.2 - agetty process is taking 100% CPU

[Bazcor]

Hi guys,

I am facing a 100% CPU issue on my proxmox server. I believe that it is the proxmox console.

Do you have any idea on how to fix it?

Thanks in advance,

Hi,

I disabled the getty service at proxmox server:

systemctl stop getty@tty1
systemctl disable gettty@tty1

Now CPU use is normal.

What could be wrong at my promox server?

Thanks in advance for any clue.

same issue here - what happens if we disabled that? any major issues?

I also have seen the same issue, but I killed the process, then the load was returned to normal.
Have to watch if it happens again.
