Need a help please: VM 245 not running TASK ERROR: failed to run vncproxy.

[papenzzo]

Hi all
Nice to be there.
-
We are using proxmox 6.3-6 on a server from So you start. Often, some VM become unavailable ( SSH access not possible, access from Proxmox also not possible).
Proxmox show this error: "VM id not running, TASK ERROR: failed to run vncproxy". And then we upgrade our proxmox server, but unfortunately doesn't solve the issue.
This often happens and make all services on VM unavailable. Every time it happens, we usually stop and restart the VM and we bring all services back.
So please someone can help us to understand the problem and to solve this issue ?

Thanks in advance

hi,

what OS is the VM running? is it possible that it goes into sleep or power save mode or similar?

We have VM with different OS (Debian, Ubuntu, Centos). But the problem is not happening for one or two specific VM. It happens to different VM at different time.

For example, today, we have restarted five vm this morning due to this issue (Pfsense VM, four other debian VM).

do you see anything interesting in the journalctl logs? maybe you are just running out of memory and the VM is getting killed

Ok i'm going to check our memory ressources and journalctl logs. Thank very much for your suggestions

Hello Oguz
Thanks for the solution idea suggested last time. So I cleaned up my Proxmox, deleted the VMs which were not in use and turned them off.
And indeed, since Wednesday, everything works fine and nothing crashed until today.
Thanks for your help and I'll keep you informed of the rest
