Something wrong in PBS 0.8.11?

[Vakon]

After update on Proxmox VE host proxmox-backup-client to 0.8.11 daily garbage collection on PBS server is switched off. It was Wednesday. And after update PBS to 0.8.11 back up process ends with an error and the VM freezes in suspension mode.
The system log on PBS generates messages for successful user authentication that were created to run backup jobs on Proxmox VE hosts for VM backup (see the first screenshot).
On Tasks page we have a message about the Bad Request.
Before updating, I changed the root password, but I never expected this effect.

Known error if I'm not mistaken. Can't find the post with the official solution. But here it is anyways.

sed -i -re 's/(:termproxy:):root:/\1:root@pam:/g' /var/log/proxmox-backup/tasks/active

Hm... Are you sure, that this string changing in /var/log/proxmox-backup/tasks/active? And yes, I read something about change @pam to @pbs, but it was necessary for another user than root...

Should be safe to do and you can always make a backup of that file beforehand.

But this is pretty much what the postinst script does - see the patch:

I hope this helps!

Ok! After replacing :termproxy::root: with :termproxy::root@pam: garbage collection began immediately. This is about problem on the second screenshot.

But still every second there are many messages about successful user authentication. Is it normal?

In addition, there was an error accessing the index file while performing garbage collection:
2020-08-28T19:47:42+07:00: TASK ERROR: Unable to open fixed index "/mnt/datastore/NameDatastore/vm/xxx/2020-08-26T12:51:37Z/drive-virtio0.img.fidx" - No such file or directory (os error 2)

It looks like this message appeared on the next garbage collection scheduling task after upgrading to version 0.8.11.
