      Sensor pod keeps getting OOMKilled despite memory limit has been increased up to 64Gb:

      $ oc get SecuredCluster -o yaml

[...]
spec:
  sensor:
    resources:
      limits:
        cpu: "4"
        memory: 64Gi

      and entity history retention disabled:

      $ oc get SecuredCluster -o yaml

[...]
spec:
  customize:
    envVars:
      - name: ROX_PAST_CLUSTER_ENTITIES_MEMORY_SIZE
        value: 0

      Furthermore, sensor logs have a very high number of these warnings:

      Warn: The same pod IP xxx belongs to 2 or more deployments
