I was wondering, Do you know of a limit on how many rootless conrainers can one run on a linux host?
Running fedora server, I have resources but once I pass about 15 containers podman starts to hang and crash.
I then need to manually delete the storage folder under ~./local/share/... for podman to work again.
It might be related to user ns keep-id flag.


Small update.
It seems to be caused by
UserNS=keep-id. when adding it to an image with a lot of files, podman hangs for a while, then crashes when doind itschown. This causes some layers to be invalid.
