Proxmox Backup Server 4.1.6 Random Hang Issue

[singhb998]

Hi Everyone,

I have been using Proxmox Backup for the past few years, but with the latest version I am facing some issues.Previously, in version 4.0.11, the Proxmox proxy service would go into a hang state, and I had to restart it manually to bring it back to normal. This caused all my running backups to fail.

To resolve this, I upgraded to 4.1.6, but now the Proxmox Backup Server itself goes into a hang state randomly. After about 10–15 minutes it comes back to normal, but during this time the GUI becomes inaccessible and after that running backups starts to fail again randomly.

I have around 200 VMs whose backups are stored on this server. I also checked CPU and RAM usage during these events, and both appear to be normal.

Could anyone help me fix this issue? Any guidance would be greatly appreciated.

Hi,
do you see any errors in the systemd journal around the time of the hang? Does the PBS host show high IO delay? What operations are being performed when this happens? What datastore backend is used (local, network share, S3, ...)?

Let me know if you find the issue for this because I'm getting the same thing on my Proxmox 4.1.5 and it just randomly hangs and I'm not sure why? I have to force power off and then reboot for it to work again and has caused some of my backups to fail.

Please also for your case provide the requested information as asked above.
