This pbs instance is using no-subscription repos and running in a virtua box vm. VBox is on the lastest version, the guest addtions are up to date and pbs is up to date. Just the webinterface is unavailable, ssh still does work. If I reboot the VM, it does work again but becomes unresponsable after a couple of hours.

Any idea what is going on here? It did work fine for the last 6 months.

Hi,
do you have any sort of uptime monitoring active? Do you see 100% CPU usage when the PBS instance is not reachable?

There is a known issue with this version [0], a tentative fix has already been applied [1] in the git repo and will be available with the next proxmox-backup-server package version. In the mean time you could downgrade to version 3.2.7 as described her [2] and see if that fixes your issue.

Glad to help, please note that the fix has been packaged with proxmox-backup-server version 3.2.9-1, the package being available in the pbstest repository at the time of writing.
