OpenShift engineering has decided to not ship Red Hat OpenShift Container Platform 4.7.17 due a regression https://bugzilla.redhat.com/show_bug.cgi?id=1973006. All the fixes which were part of 4.7.17 will be now part of 4.7.18 and planned to be available in candidate channel on June 23 2021 and in fast channel on June 28th.
Verified on 4.7.0-0.nightly-2021-06-17-075632. The cluster was 300 nodes, but we could not scale it to 15K pods on 4.7. The scalability fixes in 4.8 have really helped in that area. In 4.7 we could not scale beyond 7500 pods before nodes started going NotReady and pod startup latencies grew exponentially.
But, at 300 nodes and 7500 running pods, no segfaults/SIGSEGV were seen in ovnkube-master.
Since the problem described in this bug report should be
resolved in a recent advisory, it has been closed with a
