podman pids.max default value is 2048, docker's one is 4096 which are

sufficient for the default value (512) of rgw thread pool size.
But if its value is increased near to the pids-limit value,
it does not leave place for the other processes to spawn and run within
the container and the container crashes.

pids-limit set to unlimited regardless of the container engine.
