Nextcloud version (eg, 20.0.5): 22.2 (nextcloud:apache (offical docker image)
Operating system and version (eg, Ubuntu 20.04): Arch
Apache or nginx version (eg, Apache 2.4.25): nextcloud:apache (offical docker image)
PHP version (eg, 7.4): nextcloud:apache (offical docker image)
The issue you are facing:
After uploading photos, navigating to a a share causes the server to consume all ram (4 gigs) all swap(512megs) and OOM.
Hitting F5 shows that a few preview images were created before the crash… then consumes all ram and crashes again.
I can work around this by hitting F5 every few minutes, untill all previews on the first page are loaded… then VERY slowly scrolling down, one line at a time, allowing those previews to generate, before scrolling further.
Is this the first time you’ve seen this error? (Y/N):
N
Steps to replicate it:
- Upload a folder containing many photos (50 or so)
- Nagivate to folder in a web browser.
- Server with 4 gigs of ram OOM’s

I only have a dual core server… But it seeems that the server is spawning many many tasks to generate image previews.
my CPU usage hits 100%, and all ram is exhaused.
A slow image preview generation is preferable to a crash.
Can I configure nextcloud to only spawn 1 or 2 image preview generation threads ?
How much ram is recommended for a single instance server, with just a few gigabytes of photos?
My last server, ran fine with just 1 core, and 1 gig of ram…
But i uploaded photos one at a time over a few years.
Uploading a hand-full of photos in one go (50) killed it.
THANKYOU for any tips / hints.
