Nextcloud version (eg, 20.0.5): 26.0.0

PHP version (eg, 7.4): 8.1.17
The issue you are facing:
Is this the first time you’ve seen this error? (Y/N): N
Steps to replicate it:
- Start container
- log into NC
- Goto Files-Media folder
- Host Crash
Issues: I have a large data directory of 500GB images which I am mapping as a volume to the Nextcloud container. One of the subfolders has about 1000 files in one directory.
When I log in via (any) web browser and access the folder with 1000 images, the NC container activity goes through the roof and browser becomes unresponsive. After 1 minute or 2 the entire host systems breaks down and reboots.
Host system has ARM processor, 4 cores, 4GB ram
What I have tried:
- restrict NC container to 525MB / 1GB memory
- restrict NC container to 1.0-3.5 CPU
- add Redis caching with / without vm.overcommit_memory=1 options
I cannot stabilise the container once I enter said folder. What is NC doing there that takes so much activity and how can I stabilise the container?
