Red Hat OpenStack Platform 15 now uses Podman instead of Docker to manage containers on each host. Red Hat Engineering is currently investigating memory leaks at different levels (podman exec, SElinux and kernel) which can cause a system to crash after a few days. OpenStack Platform nodes, free memory runs low and the eventual lack of memory kills processes. These process do not become responsive again.
OpenStack Platform 15 uses `podman exec` mostly for container health checks. As a method to delay the problem, disable these health checks. On the undercloud, set the 'container_healthcheck_disabled' parameter to 'True'. On the Overcloud, set 'ContainerHealthcheckDisabled' to True in an environment file.
