@dbasunag - could you please add the hco pod log?

Comment 3 Nahshon Unna-Tsameret 2023-08-07 13:37:54 UTC

The K8s client, that is used by oc/kubectl, aggregates similar events if their frequency is too high. When HCO creates all the sub-resources, it exceeds the event rate limit, and so some of the event, are always not displayed and aggregated. This is why we miss some of the events.
