Description Andrew McDermott 2019-08-05 11:30:24 UTC

When a machineset is being deleted it is possible to get into an
endless loop where new machine's are constantly recreated as the
reconciliation logic doesn't take into account the machine set's
deletion timestamp.

This has already been addressed in upstream: https://github.com/kubernetes-sigs/cluster-api/pull/953

Comment 1 Andrew McDermott 2019-08-05 12:46:27 UTC
