The kamaji control-plane-provider override in templates/providers.yaml targeted containers[name=manager], but the upstream container is named "controller". The CAPI operator merges container overrides by name, so the intended cpu: 1 / memory: 1024Mi limits were silently dropped and the upstream default of memory: 128Mi was used, producing repeated OOMKilled restarts of the kamaji controller (exit code 137). The other three providers (core, bootstrap, infraprovider/kubevirt) ship upstream with no resources block and have no cozystack override, so they run BestEffort and are first to evict under memory pressure. Set modest limits (500m / 256Mi) and requests (10m / 64Mi) matching typical CAPI controller-manager footprint.
