Podman running container limits

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 its chown. This causes some layers to be invalid.
