Imaginary crashes- reliability question

[GogoFC]

Steps To Reproduce

Imaginary works fine for a while. Then I use Nextcloud to edit some md files or upload photos, regular stuff, then Imaginary stops working. Reboot fixes it.

Photo previews showed only blank boxes. Rebooted.

Previews stopped generating for newly added photos. Rebooted

After reboot previews were generated for the photos I added before reboot but not newly added photos.

I rebooted the VM again and that didn't help.

Then I thought I'd restart the imaginary docker cointainer.

docker restart imaginary broke the UI and I got this message:

Rebooted again, previews are now working and new ones are generating. Everything seems to work.

I just restarted the docker container again to see if UI would break again and it didn't break.

Rebooted and everything works.

Broke twice today while just editing files and uploading photos.

Build Version

27.0.0

Environment

By using the scripts

Environment Details

Ubuntu 22 server
Besides not using ncadmin, mostly default settings were selected.

Update:

Managed to break it again.

I was just creating and editing a md file, uploaded some photos then the previews stopped again. Server was up for like 30 minutes maybe. Some photos wouldn't open and some photos actually opened, but not all.

So af far as logs, I see some recent ones which I'll paste

Hi, see nextcloud/server#34262

[GogoFC]

Hey. No that's not it. This really is a bug now.
I don't have server side encryption enabled.

Imaginary works but it crashes sometimes. I'll edit this post to explain that it works in the beginning and it ocasionally crashes.
I think I'll switch over to preview generator app, might take many hours but oh well, call me old fashioned :)

Hi, see nextcloud/server#34262

Hey could you reopen this so that it will be seen, it's not the same issue. I though it would re-open after I had replied.

Any news?
