      Before this update, insufficient memory allocation caused network observability controller pod out-of-memory (OOM) kills in high-performance scenarios. As a consequence, the network observability controller pod consumed excessive memory, causing OOM kills for 500 nodes, impacting user performance. With this release, the network observability CSV memory limit has been increased to prevent OOM kills. As a result, the network observability controller pod no longer OOM kills for 500 nodes, improving stability.

      Description of problem:

      NetObserv controller pod gets OOM killed for 500 nodes perf scenario

      Steps to Reproduce:

      1. Deploy Network Observability operator
2. Run 500 nodes perf scenario

      Actual results:

      Operator pod gets OOM killed

      Expected results:

      Operator pod should not get OOM killed

       

      Upon doubling the memory in NetObserv CSV, the pod runs fine
