The `small` preset (512Mi) is not sufficient for the Strimzi 0.45 / Kafka 3.9 image baseline. With the default Strimzi heap formula (Kafka 50%, ZooKeeper 75% of container memory limit), the remaining non-heap budget (Metaspace, code cache, direct buffers, JMX javaagent, embedded Jetty admin server, KRaft migration endpoints, thread stacks) consistently overflows the 512Mi cgroup limit at startup, leading to OOMKilled (exit 137) and CrashLoopBackOff for both Kafka and ZooKeeper pods. Bump the default `resourcesPreset` for kafka and zookeeper from `small` (512Mi) to `medium` (1Gi). The `small` preset stays in the enum so existing deployments that pin it are unaffected; only the default changes. Signed-off-by: Ivan Okhotnikov <ivan.okhotnikov@aenix.io>
