The first 5 failures I looked at all look to be the same cause:
[sig-arch] events should not repeat pathologically expand_less 0s { 1 events happened too frequently event happened 115 times, something is wrong: node/ip-10-0-117-116.ec2.internal hmsg/a4cafcb105 - reason/ConfigMapUpdateFailed Failed to update ConfigMap/csr-controller-ca -n openshift-config-managed: Operation cannot be fulfilled on configmaps "csr-controller-ca": the object has been modified; please apply your changes to the latest version and try again (12:43:31Z) result=reject }
This test is intended to catch excessive event spamming and load on etcd, the limit is 20 identical events, and here we're seeing hundreds. This is caused by different copies of cert rotation controller rewriting each other changes.
