Hi, after setting to 8G limit the issue seems to have resolved. I wonder if we should consider updating the scaling / performance doc: https://docs.openshift.com/container-platform/3.11/scaling_performance/scaling_cluster_monitoring.html#cluster-monitoring-capacity-planning As noted in the initial bug description, the customer's cluster is actually smaller than the smallest test on the chart, and yet needed more memory. Are there certain situations where more memory is required? I'm not sure if this is a priority since it's 3.11, but I wonder if we should tweak the document if this is a common issue. Otherwise I think we can close the bz. 3.11 PR - https://github.com/openshift/openshift-docs/pull/29502 4.5-4.7 PR - https://github.com/openshift/openshift-docs/pull/29503 Simon, PTAL at the above PRs and let me know if more details are needed in the new note. Thank you.
