Hi Severin, that's a pity and looks like a bug, because the docker
documentation says
https://docs.docker.com/engine/reference/commandline/run/
<html>
<body>
--pids-limit | | Tune container pids limit (set -1 for unlimited)
-- | -- | --
</body>
</html>
Do you have an idea what to set with docker 20 on your setup? I did not find
much about this in the docker 20 release notes
https://docs.docker.com/engine/release-notes/ .
